Send Data
• Even addresses must always be used for indirect addressing (@ 0001, @b0173, etc. are
prohibited).
• For details of indirect addressing, see PC's programming manual.
• F-204 instruction must always be used in conjunction with the F-202 (OPCH) instruction.
• After turning ON the input signal of F-204, keep it ON until the finish of the execution of the
instruction. If the input signal is turned OFF during execution of the instruction, the instruction
ends in an incomplete condition. Under this condition, next, when an F-204 instruction is given, it
will come to a “communication jam,” and the instruction will not be executed. Turn the power OFF
and then ON again for recovery.
[*1] Setting range of “S” is for JW model PCs. For ZW model PCs, setting range is 0000 to
19777.
[*2] In case that the network module of the assigned module number is not installed.
[*3] In case that the channel is used with the other SEND/RECEIVE instruction.
This instruction is executed after end of execution of the previously given instruction, and
flag sign is changed into “communication busy” from “communication jam.”
[*4] In case that response from the target station does not come within the time-out time.
