User Communication (SEND, RECV)

This is used to define communication frames in the protocol editor, sending or receiving the frames in a program.

User communications is the mode that other companies’ protocols can be defined in the CIMON PLC to communicate communications modules with other devices. Diverse communications protocols are used according to manufacturers and all the protocols cannot be built in. And if a protocol is defined properly to an application field and a program is written, communications with other devices is available according to a defined protocol. If a protocol editor is used to define protocol frames (In the CICON), it is available to write and edit other manufacturers’ protocols. To use as user communication mode for correct data communication, the information about the contents of the protocol used is to be correct and a program using the instructions to control sending/receiving in a PLC as well as editing frames be written. This chapter explains the communication specifications and the directions for use of user protocols.

The modes of communications modules operated as a user protocol are as follows.

But, Make sure the version before using user protocol (SEND, RECV) function.

To use user protocols, a version should be higher than the versions described above.

Otherwise, consult with the head office to upgrade.
