■Program example

The following shows an example of a program that receives response data from D20 after the request data is set from D10 to

• Before executing the G(P).CEXECUTE instruction, the user function must be registered using the C intelligent function

module dedicated function (CITL_EntryDedicatedInstFunc). If the user function is unregistered, a 'user function

unregistered error' (1800H) will be returned. In addition, 1 user function can be executed by the G(P).CEXECUTE

instruction. If you want to run multiple functions, prepare the data for identifying functions in request data, then call the

functions distinctly using the conditional branches in user function.

• The G(P).CEXECUTE instruction cannot be executed additionally while another G(P).CEXECUTE instruction is being

executed. (If attempted, the instruction is not processed.)

• The local device and the file register for each program are not available for setting data.

• Operand must be specified even when request data and response data are not required.
