4. 2 Communication Speed When communicating via modems there are two different definitions of communication speeds that you should be aware of The DTE Speed or line rate is the serial communication speed between the modem and the device connected to its RS232 port Most modems can automatically detect the RS232 speed of the device and can assume any speed from 1200 2400 all the way to 115 200 bps The first ASCII character they receive from the device will determine the DTE speed that the modem will use to communicate with the device The modem to modem communication speed is what you read on the modem specifications such as 33 6Kbps 56Kbps etc When two modems are connected they automatically negotiate for the best speed to communicate between the two of them based on the quality of the phone connection and the maximum speed that both modems are able to achieve We usually have no control of what speed they choose to communicate But one thing is for sure which is that the modem to modem speed is always lower than the DTE speed Since the default communication baud rate of the M series PLC s RS232 serial port is 38 400 bps the PLC should send a modem initialization string to the modem on the first scan pulse so that the modem can recognize its default DTE speed i e 38 400 bps in order to talk to the PLC E g To reset the modem you just have to send an ASCII string ATZ to the modem using the following TBASIC command PR

17. For example you don t need to update the value of a variable displayed on the LCD screen any faster than the human eye can read them So using a 0 5s clock pulse may be sufficient and this will not take up too much CPU time for the display For slow processes such as heating a 1 0s clock pulse to monitor temperature change is more than sufficient IMPORTANT 1 When the CPU scans the ladder logic to a circuit which contains a CusFn and the execution condition of the circuit is TRUE the corresponding CusFn will be immediately executed This means that the CPU will not execute the remaining ladder circuits until it has completed execution of the current CusFn Hence if the CusFn modifies a certain I O or variable it is possible to affect the running of the remaining ladder program 2 Note that the INPUT n variables contain data obtained at the beginning of the ladder logic scan and not the actual state of the physical input at the time of the CusFn execution Thus it will be futile to wait for the INPUT n variable to change inside a CusFn unless you execute the REFRESH statement to refresh the physical I O before you examine the INPUT n variable again 3 Likewise any changes to the OUTPUT n variable using the SETBIT or CLRBIT statement will not be transferred to the physical outputs until the end of the current ladder logic scan Hence do not wait for an event to happen immediately after executing a SETBIT or CLRBIT statement on an OUTPUT
