COM port 1 - baud rate
2400–115200bit/s
NOTE
•
The communication format and baud rate of the PLC should be set to match
the connected device.
•
When the RS485 port (COM port 1) of FPG-COM4 is used, set the baud rate
in the system registers to either 19200bit/s or 115200bit/s. Set DIP switch
SW1-2 of the cassette to the same setting (see page 162).
•
When setting the station number using the system registers, be sure to set
the switch on the unit to 0.
•
FPG-COM3: Bridge the E terminal and the free (-) terminal on the first and
on the last station of the transmission line to terminate the data bus.
FPG-COM4: Set SW1-1 to ON on the first and on the last station of the
transmission line to terminate the data bus. There is no terminating resistor
at the RS232C port.
•
C-NET adapter: Set the DIP switches to terminate the data bus.
Programming
There is no programming required on the slave. Only the station number and the
communication parameters must be set in the system registers. The program for the master
side must send and receive commands according to the MEWTOCOL-COM protocol.
MEWTOCOL-COM contains the commands used to control and monitor the slave operation.
If a software program such as PCWAY is used on the computer side, PLC data can easily be
read and written without having to think about the MEWTOCOL-COM protocol.
