Dear All, S7-300 CPU 315-2DP is installed with Unidrive M700. there are total 8 drives which are connected to PLC via Profibus. I am using command RDSYSST to read the status of a drive if it is healthy or tripped to maintain alarm history. I am using DB3 in DR. Data in DB3 is being shown as follows, DATA[0] = 00 DATA[1] = F0 DATA[2] = 07 DP address of the drives is 12,13,14,15,16,17,18 and 19. Problem is that values in DATA[1] and DATA[2] remains F0 and 07 either the drive is tripped or not. PLC shows SF fault in any drive is tripped but values in DB3 remains unchanged. Cannot send PLC program because file is larger than 3MB. Some screens shots are attached for reference. can anyone suggest the solution please? waiting for reply.
