Ti aes 8 3 INTERNATIONAL Chapter 9 Interrupts Chapter 9 Interrupts Tr v TRIANGLE 17 RESEARCH INTERNATIONAL Chapter 9 Interrupts 9 INTERRUPTS 9 1 Input Interrupts During normal PLC ladder program execution the CPU scans the entire ladder program starting from the first element progressively solving the logic equation at each circuit until it reaches the last element After which it will update the physical Inputs and Outputs I O at the end of the scan Hence the location of a logic element within the ladder diagram is important because of this sequential nature of the program execution When scanning the ladder program the CPU uses some internal memory variables to represent the logic states of the inputs obtained during the last I O refresh cycle Likewise any changes to the logic state of the outputs are temporarily stored in the output memory variable not the actual output pin and will only be updated to the physical output during the next I O refresh You can see that the CPU will only notice any change to the input logic state when it has completed the current scan and starts to refresh its input variables The input logic state must also persist for at least one scan time to be recognized by the CPU In some situations this may not be desirable because any response to the event will take at least one scan time or more An interrupt input on the other hand may occur randomly and the CPU will have

The EZWire1616 features a special NS command tag lt TCPCONNECT xxx xxx xxx xxx portno gt that allows you to connect to any server to download data However since the PLC does not have a lot of memory for storing incoming text data it is not suitable for downloading information from a commercial website that sends many kilobytes of data in a single download It can however be very useful to connect to some servers that send small amounts of information For example there are many Internet Time Servers on the Internet that allow users to synchronize their computer clocks via the Internet The service responds to time requests from any Internet client in several formats including the DAYTIME TIME and NTP protocols The simplest are those that send responses in ASCII data and you can extract the date and time information from the response ASCII string once you know the format You can search on the Internet for a suitable timeserver and use the TELNET program on your PC to access them to examine their display format Most timeservers listen either on port 13 or port 123 so you need to specify the port number together with their IP address when sending the lt TCPCONNECT gt command Format lt TCPCONNECT IP address portno of time server gt Response none Successfully connected to the Modbus TCP server of the specified IP address ERR 05 Prev Conn ON Another NS command has been executed and left the client socket opened but did no

To transmit a command the master controller must first enable its RS 485 transmitter and then send a multi point command to the network of controllers After the last stop bit has been sent the master controller must relinquish the RS485 bus by disabling its RS485 transmitter and enabling its receiver At this point the master will wait for a response from the slave controller that is being addressed Since the command contains the ID of the target controller only the controller with the correct ID would respond to the command by sending back a response string For the network to function properly it is obvious that no two nodes can have the same ID You can use the Setup Serial Port command in TLServer to set the ID for each EZWire1616 You can also use the IW Host Link command to set the device ID Also all nodes must be configured to the same baud rate and communication format Care should be taken to ensure that the power supplies for all the controllers are properly isolated from the main so that no large ground potential differences exist between any controllers on the network 15 5 4 Multi Master RS485 Networking Fundamentals Since the EZWire1616 is capable of sending out network commands the obvious question is whether multiple masters are allowed on the RS485 network It is possible to have multiple masters on a single RS485 network provided the issues of collision and arbitration are taken care of There are several means to ac

FTP client and the FTP server The second connection is the data channel where only the file content or the file directory data are being transferred There are two transfer modes Active mode and Passive mode Active mode requires that the server establish a data connection back to the client Passive mode on the other hand requires that the client also be the one to establish the data connection i e For passive mode both the command and the data connections are performed by the client the PLC in this case The PLC has been designed to use only passive mode to transfer file to the FTP server Passive mode is preferred because that is the only way to transfer file if the FTP Server is located on the Internet The alternative active mode transfer requires the server to make a data connection back to the PLC that is sitting behind a router firewall and that can be problematic unless the router is specifically configured to forward the data port to the PLC 18 6 2 PLC FTP Upload Procedure In order to upload file to the FTP Server the PLC would use the PRINT 4 lt TCPConnect XXX XXX XXX XXX 21 gt command tag to connect to the FTP server port 21 to establish the command connection to the FTP Server The PLC uses its PRINT 4 to send and INPUT 4 to receive ASCII text strings from the FTP server via the command channel The PLC would then send the command PASV to inform the FTP server that it wants to transfer a

MODBUS TCP server simultaneously This means that all F series PLCs are ready to interface directly with many third party industrial control devices that support the MODBUS TCP protocol These include the SCADA software HMI hardware OPC Server HVAC controllers and many other industrial control devices In addition the EZWire1616 can be used both as a MODBUS TCP SERVER as well as a MODBUS TCP CLIENT simultaneously This means that the EZWire1616 can readily read data from any device that has a MODBUS TCP server such as flow meters AC DC drives HVAC elements RTUs network sensors etc Itis also possible to perform peer to peer networking with other MODBUS TCP controllers e g another F series PLC over a LAN or over the Internet 2 5 1 Connecting To The PLC s MODBUS TCP Server By default the F series CPU supports up to 3 simultaneous MODBUS TCP connections You can change the number of simultaneous MODBUS TCP connections from 2 to 5 using the F series Ethernet Basic Configuration program as described in Section 2 1 The PLC will listen on the default well known MODBUS TCP port 502 for one or all of the connections However it is also possible to define a secondary port number as described in Section 2 1 7 Note that if you define a secondary port number then only one of the MODBUS TCP connection will listen on port 502 and the remaining connections will only be listening on the secondary port number If you have a MODBUS TCP c

Name You can assign up to 16 ASCII characters any character in naming a PLC The node name is currently not used by the network router so it is merely a convenient name for user to identify a PLC 2 1 10 Username and Password FServer only You can use the username and password feature to prevent unauthorized access to the FServer It adopts the same proprietary encryption scheme used in the TLServer and TRILOGI software to encrypt the password transmission However unlike the TLServer that allows you to define unlimited number of usernames and passwords the FServer only permits a single set of username password and this is limited to a length of 16 characters Although you may define the passwords for a USER and a VISITOR privilege 2 1 11 Use Username Password Yes No In applications where there is no danger of unauthorized access to the PLC via FServer you can elect not to use the username password With the No option selected the TRILOGI client can log in to the FServer using whatever username and password since FServer will bypass the username and password authentication and allow the client to log in 2 1 12 Access Level You can define the access level that the TRILOGI client is permitted to operate under on the PLC Three access levels are currently defined 1 for Programmer 2 for User and 3 for Guest Please see the i TRILOGI Programmer s Reference manual for the definition of the access levels Ti aes 2 6
124. Otherwise if the voltage of the load power is lower than the voltage of the CPU power the output LED will light up even when the output driver is not energized This is because the current could flow out of the PLC s output into the lower voltage load power supply and therefore light up the LED This can be very confusing to users even though it should not damage the LED Should this happen you will need to add a series diode to the output terminal to block the output LED currents from flowing through the load and back to the load power Please use only an industrial grade linear or switching regulated power supply from established manufacturers Using a poorly made switching power supply can give rise to a lot of problems if the noisy high frequency switching signals are not filtered properly Always place the power supply as close to the PLC as possible and use a separate pair of wires to connect the power to the PLC Keep the power supply wires as short as possible and avoid running them along side high current cables in the same cable conduit The EZWire1616 PLC will be reset when the power supply voltage dips below 9V In a high noise enviroment you may consider connecting a 470uF to 1000uF 50V electrolytic capacitor near the power supply connector to suppress any undesirable voltage glitches from conducting into the PLC If other high current devices such as a frequency inverter were to affect the operation of the PLC you should then also

PU firmware automatically schedules the order of the command response packets whether it is originated from the client or from the PLC itself so that the Modbus TCP command from the client will be responded to in the correct order and in a timely manner 19 2 Application Ideas for Modbus TCP Gateway The Modbus TCP gateway function can be very useful for many large area control systems such as a building automation system A master EZWire PLC is linked to many Modbus RTU slave controllers via RS485 bus distributed across an entire building The master PLC can perform sophisticated control functions since it has read write access to ALL the Modbus RTU slaves it connects to At the same time a Modbus TCP client software such as a Building Management System BMS can access any registers in the master PLC or ANY of the slave Modbus RTU controller directly via the master PLC acting as a gateway for the slave PLCs 19 3 Configuring The PLC As Modbus TCP Gateway The command used to define a serial port to become Modbus TCP Gateway serial port is as follow SETSYSTEM 12 n Where n 1 2 or 3 for COMM1 COMM2 and COMM port This statement must be run once could be during start up via 1st Scan pulse to configure the serial port n to be used to send out RTU commands and received RTU responses If SETSYSTEM 12 n is not run then the Modbus gateway function will be disabled Here is how it works A Modbus TCP client such as a SCADA HMI etc
