Dear all My name is Kishor dalwadi working on siemens PLC recently i am facing one problem of communication between S5 plc and master drives simovert dc. The details description is that in plant there is honeywell dcs system is installed.and there are aprox.80 master drives simovert dc are installed in the plant which are communicate with S5 115 u plc through RS 485 network.with the help of modules 6ES5-524-3UA13 (total4 nos qty).Main CPU in S5 plc is 6ES5-816-1BB11 There is one more modules 6ES5-524-3UA13 for the S5 115 plc and honeywell dcs.previously whole system is working fine without problem.means all master drives commands and status are available on honeywell scada. now one day UPS power failure happen in the S5 plc.after that master drives are not taking any command from the S5 plc though there is start command available from honeywell dcs to S5 plc.but status of the drive is transfer to S5 plc via communication.(command to S5 plc is reveived from Honey well DCS through communication) So that the recent status is that we could not start master drives in auto mode from the main dcs.when we put master drive in auto mode there is code F008 shown in the master drive screen.it means drive is not ready for auto control. Also we checked and confirm that communication between DCS and S5 plc is working fine.also status from drive to plc and plc to dcs is working ok.only start command is not taken due to above error. i am very thankful if any body help me in this regards. i am also attaching the S5 program of the S5 plc.
