1. fields You have to ensure that the IP address you use is unique and not already been assigned to another device on your network The static IP address should also be outside the scope of addresses of the DHCP server Please ask your system administrator to assign you a valid static IP address for your XServer so that the System Administrator can keep track of a list of IP addresses that have been assigned Auto IP If the XServer cannot find a DHCP server and you have not manually assigned an IP address to it XServer will automatically select an address from the AutolP reserved range which is fom 169 254 0 1 to 169 254 255 1 The XServer sends out a ARP request to other nodes on the same network to see whether the Ethernet XServer User s Manual selected address is being used If the selected address is not in use then XServer will use it forlocal subnet communication If another device is using the selected IP address the unit selects another address from the AutolP range and reboots itself After reboot the unit sends out another ARP request to see if the selected address is in use and so on until it finds a suitable IP address AutolP can be disabled by setting the XServer s IP address to 0 0 1 0 This setting enables DHCP but disables AutolP GateWay IP Addr The Gateway IP address lets XServer communicate to other LAN segments or to the Intemet The gateway address is usually the local IP address of the router whe2. COM Port Baud Rate The XServers RS232 COM port has to be set to the same baud rate as the PLC s for successful communication The default baud rate is 38400 bps which is the default baud rate of M series PLCs If you have defined the PLC using the SEIBAUD command to another baud rate then you have to change this setting to match the PLC s baud rate Note that XServer only supports a single communication frame format of 8 data bit 1 stop bit and no party Please note that this COM port setting only takes effect when the XServer is rebooted into Operation mode i e reset with DIP Switch 1 in the OFF position The XServer only uses baud rate of 38400 bps during Configuration mode regardless of the value of this setting 4 Operating The Ethernet XServer With the XServer connected to the Ethemet and the PLC and the DIP Switch 1 at the OFF position tum ON power to both the XServer and the PLC and wait till the green RDY LED lights up The XServer will now be ready in Operation Mode Note that it may take 5 to 20 seconds for the XServer to be ready which is much longer than the PLC typical boot up time Hence if you are programming the PLC to use the 1stScan pulse to initialize the XServer your program will have to check for the operational readiness of the XServer before issuing any command You can let the PLC send the lt IP gt command described later to check for the readiness of the XSe
3. not allow the PLC to use SIX and ACK handshaking scheme with the XServer when the XServer is in the midst of transmitting commands to the PLC The tumaround delay can also give problem during arbitration between the PLC and XServer All NS commands begin with a string enclosed within the angle bracket called a tag e g lt EMAIL gt lt CONNECT gt Most NScommands end with a closing tag lt gt except the lt REMOTE gt tag which ends with a lt REMOTE gt closing tag Depending on the command type the XServer may retum one or more response strings to the PLC from which the PLC can read to determine if the command has been executed propery The PLC can only interact with the XServer by means of TASC INCOMM OUICOMM INPUT and PRINTcommands It uses the PRINTand OUICOMM to send NS commands to the XServer and the INCOMM and INPUT to receive the data from the XServer However this can present a problem because if the XServer is busily passing data to and forth to the PLC in response to a client then an untimely NS command sent by the PLC can be mistakenly passed back to client program and disrupt the on going communication with the client In addition the PLC buffer up to 256 bytes of serial data coming through its COMM port which includes those host link commands it received in previous communication session Therefore if the PLC executes a simple NPU statement all it receives

5. will likely be an old host link command sting it got in the previous communication instead of the expected response Sting thatis a result of the NS command it sent In order to resolve this potential conflict the XServer implements an arbitration scheme which when used propery can allow the PLC to send NS commands while in the midst of Communicating with XServer as a Slave Here is how it works Ethernet XServer User s Manual 1 2 3 4 The PLC should send a STX character ASCII 2 to the XServer to signal to the XServer that it wishes to send a NS command The XServer upon receiving the STX character will complete all curent communication exchanges with the PLC and put new communication exchanges on hold temporanily It will then send an ACK character ASCII 6 to the PLC to signal to the PLC that it is ready to accept the NS command After sending the STX character the PLC should continue to read from its serial input port one byte at a time until it receive an ACK character from the XServer At this point the PLC would have cleared its seral input buffer and having received the ACK character from the XServer it can now proceed to send the NS command to the XServer and use the INPUI command to read the response conectly from the XServer After the XServer completed the NS service request sent by the PLC it will resume execution of suspended communication sessions with other clients Thus the client will not los

15. g PLC program without using any of the XHMI1 variables it should still be pretty staightforward to integrate the contol elements of the XHMI1 applet into your exsting program For example If you want a button on the XHMI1 contol panel to provide parallel contol action to an actual input button then you just need to connect the contact of the associated relay 129 to 136 to that input contact Likewise If you wish to show an exsting alarm condition on the XHMI1 applet panel all you need to do is to use the contact of an output or relay that represent the alarm condition to drive the relay coil i e relay 137 to 140 that is associated with the red lamp If you wish to show the value of a TBASIC variable X on the first numerical text field on the XHMI1 panel then you just need to assign X to EMUNT1 each time its value changes Or you can also do so periodically using a clock pulse E g use a 0 5s clock pulse to execute a custom function that contains the following statement EMUNT1 X If say you have modified a numeric variable EMUNT1 to EMUNT4 and want to notify the PLC program of the update so that the PLC program can respond to it immediately then perhaps the most direct way is to program one of the green buttons to tigger the required Update action in the PLC program Altematively you can set up a clock pulse so that the PLC program can periodically check for changes in the variable EMUNT n and cany out the necessary
