  1. @Wasan Good day Wasan, in a M221 PLC program I am using a counter and I must make sure the last counted value is remembered during power outages. Where can I put this system bit 1 (%S1) in a rung to do this? I search in the M221 Help but can't find any, just descriptions only. Please show me where to use this system bit.   Thank you
  2. @Wasan Good day Wasan, I tried to use the same setup of the Example you gave on the Read_Var to read registers of four Toshiba Softstaters (Manual link:  http://sunnice.com/manuals/(71105)%20Toshiba%20TMS7%20Users%20Manual.pdf) but cannot read anything from the Soft starters. The Toshiba Softstaters' RS485 port can only communicate on MODBUS ASCII, I tried to change the PLC Serial Link settings to MODBUS ASCII but still cannot, How can I configure Modbus ASCII on my M221 PLC (SoMachine Software)?   Than you
  3.   @Wasan5 x M221CE24T PLC CONTROLLERS (1 MASTER AND FOUR SLAVES), I tried and got them finally communicating through our network but one problem, when one of them goes offline/power off, the entire communication fails. Though four of them online they still cannot communicate with master until the one goes off comes back online. How can I make master communicate separately with its slaves and I can identify which slave goes off. Attached is the PLC Program of the master Controller (M221CE24T)   Thank you   MASTER PLC_10.190.153.232.smbp
  4. @Wasan I followed the example you gave, it is perfectly reading the four soft starters.   I was also trying to read and write between M221 PLC using the Read_Var/ Write_Var via network (3_eth1 not 1_SL1) but I still cannot get it right, every time I try, I still make wrong setting somewhere, please help me.   Thank you
  5. @pturmel Good day pturmel, How long does it take for a Modbus Master to read from/ write to its slaves?   Thank you
  6. @Wasan Thank you very much for help Wasan! I will follow this.
  7. @Wasan Thank you, actually 12 registers, Register 3 to 14 (Motor Current to Soft starter fault codes). I was using timers to read two soft starters. Instead of this EXCH/MSG please help me how to use this READ_VAR. Attached is my PLC program and the list of registers to read.   Thank you once again for help Chapter 6.pdf MY PLC PROGRAM.pdf
  8. @WasanThanks Wasan, attached is the comms manual WEG-ssw06-serial-communication-manual-0899.5731-1.6x-manual-english.pdf
  9. I can read registers of one soft starter, I tried to read registers of four soft starters using a M221 PLC but I can't! Please anyone explain me on these MSG1/2 to read all the soft starters' registers using a master PLC (M221) Thanks
  10. pturmel, another question on the same subject,  I tried to read registers of four soft starters using a M221 PLC but I can't! Please would you explain me on these MSG1/2 to read all the soft starters' registers using master PLC (M221)   Thank you
  11. Thank you very much PTurmel, I will try that
  12. I am new to MRPLC forum, how can I be selective to registers which I want to read instead of reading all consecutive registers from a single slave device. Attached is how I wrote to read 11 consecutive registers from a soft starter using Function Code3.
  13. This explanation helped me too, I followed up and can read (read only) registers of one soft starter. I tried to read registers of four soft starters using a M221 PLC but I can't! Please would you explain me on these MSG1/2 to read all the soft starters' registers. Attached is how I wrote to read read 11 registers of a soft starter. Thank you in advance
