When an OPR is not required
Control can be carried out ignoring the "OPR request flag" ( Md.31 Status: b3) in
systems that do not require an OPR.
In this case, the "OPR parameters ( Pr.43 to Pr.57 )" must all be set to their initial
values or a value at which an error does not occur.
OPR from peripheral devices
"Machine OPR" and "fast OPR" can be executed from the test mode of the peripheral
device.
Refer to GX Configurator-QP Operating Manual for details on OPR from the peripheral
device.
