Refer to F-204 and F-205 for the combination of F-204 and F-205. [ ]
•After turning ON the input signal of F-202, 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-202 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.
[ ] F-202 instructions must always be used in conjunction with the F-204 (SEND) or F-205 (RCV)
instruction.
