Precautions for programming
● The station number of the FP7 multi-wire link unit can be set by the PMSET/pPMSET
instruction only when the station number selector on the unit is set to 0.
● Describe the UNITSEL instruction immediately before the PMSET/pPMSET instruction.
Specify the slot number of the unit from which the parameters are acquired for [S1] and
specify 0 for [S2].
● Checking of the processing result should be carried out when bit 15 (process in-progress
flag) of the area specified by [D] is switched from 1 to 0.
● The content set by the PMSET/pPMSET instruction is not held in the case of power outage.
Turn on the power supply again and switch to RUN mode to return to the configuration
information set in the tool software.
● When setting it for the FP7 multi-wire link unit, it cannot be used in an interrupt program.

Comparison between the PMSET instruction and the pPMSET instruction
Instruction Characteristics
PMSET
The processing result is checked during the operation processing of the PMSET instruction.
(Note
1)
Adv
anta
ge
The PMSET instruction can be executed without any restrictions for different COM ports.
Disa
dvan
tage
It is necessary to turn ON the execution condition of the PMSET instruction until the end of
processing, and turn OFF the execution condition at a scan in which the end of data
transmission is confirmed.
pPMSET
(Note 1)
The processing result is checked at the end of a scan.
(Note 1)
Adv
anta
ge
The parameter change processing is performed only once by turning on the execution
condition at the time of data send.
Disa
dvan
tage
Up to 16 send operations can be performed simultaneously to different COM ports. (The
total of simultaneous usage of SEND, RECV, pGPSEND, GPTRNS, and pPMSET
instructions.)
(Note 1) Checking of the processing result means that the result of the parameter change processing is stored
in [D].

It can be changed only when the rotary switch on the
front panel of the unit is set to 0. When using the PLC
link, set it in the range of 1 to 16.
