chelebi_yn Posted May 31, 2016 Report Posted May 31, 2016 (edited) Hello everyone. If anyone knows how an empty slot on base is defined by "system monitor" service of GX Works which shown in attached picture? I think this information is read from any CPU register address(Maybe SD or SM and etc. registers). But I don't know exactly which address is deploying an information about empty slot on base. Thanks.

Delbert Posted June 2, 2016 Report Posted June 2, 2016 Not exactly sure what your asking. The rack layout is assigned in the PLC Parameters on the I/O Assignment tab. The number of points occupied by an empty slot is also assigned in the PLC Parameters on the PLC System tab. Quote
chelebi_yn Posted June 3, 2016 Author Report Posted June 3, 2016 We make rack layot in PLC Parameters on the I/O Assignment tab. But i think System Monitor tab read data about base slots from CPU registers not I/O tab ( empty slot number or name of module on used slot). Because if i assign module slot on I/O tab and i take module from base or never put in module on base then I/O tab show there is a module but System Monitor shows the slot is empty. I want to know System monitor how reads information about base slots or which adress of CPU (D, SD, SM) is storing information about slots of base unit. Quote
Delbert Posted June 3, 2016 Report Posted June 3, 2016 SD240 - SD246 might have the information you are looking for. Also SD1400 -SD1431 contains the Module Verify Errors Quote
