PREDEFINED PROTOCOL SUPPORT
FUNCTION
This chapter describes predefined protocol support function (serial communication protocol support function).
For details about built-in Ethernet protocol support function, refer to Ethernet communication manual.

Function Summary

With predefined protocol support function, data can be sent and received between the counterpart device and CPU module
according to the protocol of the counterpart device.
Predefined protocol support function uses the S(P).CPRTCL instruction.
The S(P).CPRTCL instruction can simultaneously communicate on 2 channels by specifying the channels.
• Up to eight protocols can be executed consecutively. (1 send packet, 16 receive packets in one protocol)
• The protocol can use the general-purpose protocol library, which is pre-registered in the serial communication protocol
support tool. Additional protocols can be registered.
• Data transfer is enabled when the connected equipment supports non-protocol serial communication.
• The overall distance is 1200 m maximum. (Applies only when configured by FX5-485ADP)
Engineering tool
Set the necessary protocol, and write in protocol setting data to the CPU module.
