Predefined protocol support instruction

This section explains the function, operation and programming method of the S(P).CPRTCL instruction.
For details on the expression and executable format of the S(P).CPRTCL instruction, refer to Programming manual
(Instructions, Standard Functions/Function Blocks).
S(P).CPRTCL
This instruction is used to execute the predefined protocol registered with the engineering tool via RS-485 built in the CPU
module, or the communication board and communication adapter installed to the CPU module.
