CALL PLCINIT Statement
Purpose:
This command is used to initialize communication with the FX. CALL
PLCINIT must be issued prior to any other communication (reading or
writing) to the specified PLC. CALL PLCINIT initializes the BAUD rate to
9600 Baud, 7 data bits, even parity. Either COM 1, COM 2, RS422, and
RS232 can be specified. Note that on T-60 ’s COM1, RS422 is
recommended. If the CALL PLCINIT command fails, the T-60 Series unit
will break your program and generate the error message “PLC link not
established.” If this make sure that the connections and communications
configurations are correct. If they are OK, check to make sure that the FX is
powered up and ready to accept Commands.
