■Communication execution status output device
The following shows the timing of operation of the communication execution status output device (d2) according to each
communication status, and the special relays which operate at the same time.
Operand Timing of operation
(d2) Turns on while the instruction is executed and
turns off in the status other than while the
instruction is executed.
*2
(d2) + 1 Turns on when the instruction is completed
normally and turns off when the instruction is
started.
*2
(d2) + 2 Turns on when the instruction is completed
with an error and turns off when the instruction
is started.
*1 SM8401 (CH1) or SM8421 (CH2) turn on, when SM/SD for FX3 compatible is set.
*2 (d2) + 1 turns on when the instruction is completed normally and (d2) + 2 turns on when the instruction is completed with an error, so
that whether the instruction is completed normally or with an error can be judged.
Precautions
• The channel which uses the ADPRW instruction must be set to the master station by the GX Works3. (Page 27 Fixed
Setting) When it is not set, the device does not operate even though the ADPRW instruction is executed. (Also no error
occurs.)
• If the program stops due to error, the device value is turned off if a non-latch device is designated as the communication
execution status output device. Specify a latch device to keep the communication state output.
