2.10 Communications with a JTEKT PLC (TOYOPUC Protocol)
Using the MSG-RCVE Function with the MP3000 as a Slave
2-278
Setting the Remote Device (JTEKT PLC)
Use the following procedure to set up the JTEKT TOYOPUC PLC.
1. Set the Ethernet settings and baud rate using the DIP switch on the 2PORT-EFR Module.
2. Start the PCWIN.
3. Set up the I/O Module. The identification code for a 2PORT-EFR module that has been set up to
use Ethernet communications is “B3”.
4. Set the link module name. In the Link Parameter Dialog Box, select the rack number and slot
number to assign to the 2PORT-EFR module, and set the link module name to Ethernet.
5. Set the communication parameters.
Note: When communicating with TCP and the open protocol setting on the 2PORT-EFR is set to TCP Active Open,
execute the MSG-RCVE function on the MP3000 to receive messages. If the open protocol setting on the
2PORT-EFR is set to TCP Destination - Specified Passive, or TCP Non-Specified Passive, execute
the MSG-SNDE function in the MP3000. The MP3000 is capable of operating as a TCP active node when
using the MSG-SNDE function, and as a TCP specified passive node or TCP non-specified passive node when
using the MSG-RCVE function.
TOYOPUC PLCs are manufactured by JTEKT Corporation.
