T J SHARON posted a topic in CX-ProgrammerHI All, I have an issue with my SCU32 communication. Back ground Two SCU32s (top and bottom side) connected via a 1100M datacable using port1 ( 9600bps, 8-2-E, start code FF, end code FE, Tx save to d1000-d1200 , Rx save to d2000-d2200). PORT2 of bottom SCU32 is connected to a compass( 2 wire, 8-1-N, 19200 bps, serial gateway MODBUS ). Refer to photo Issue Without compass, the receiving data at top is very stable and is didn't see any fluctuation. But if is compass is connected at bottom side port2, there is a fluctuation at the top side RX data(specifically d2000-d2005 ) . I checked the data a bottom side TX (d1000-d1200) and it is stable. Only after sending the data and Receiving at Top side, then only the starting words fluctuate. I am not sure sure what is wrong, I am using logical ports for the DTXDU/DRXDU and compass. Appreciate all your feedback and suggestions.
T J SHARON posted a topic in CX-Programmerhi all, I am using SCU32 ( unit1, port2, 2wire and termination OFF) to get the RS485 data strings from the compass with setting 19200bps, 8 databit, 1 stop bit & No parity. I can send the TX string ( 01 03 00 01 00 03 54 0B) from D100 memory and write the Rx data to D2000 (01 03 06 xx xx yy yy zz zz CC CC). But the whenever the there is no RX data, The TXdata bounce back to RX. (refer to video, d100 is TX, D2000 is RX). I also tried wth SCU32 termination resistance ON. Same thing. I am not sure what is missing. Should i use different logical Port for TX and RX ? EDITED: Just tried another scenarios 1) removed the connector and tried , D2000 - was written the TX values 2) Disable the RX changing LD from P_On to P_Off. D2000 - was written to #0000 0000 0000 0000 I am not sure what is happening., Open connection also TX data bounce back to RX Appreciate all help Thanks a lot video1.mp4
HI , Thanks a lot for the reply & help on previous topic. Now i setting up a new system with 2x CJ2M CPU13 and 2x SCU32 and the connection via 1000M RS485 cable. May i know the best communication to use for the serial communications? Regards, TJ SHARON.
KuYaRi posted a topic in CX-ProgrammerHi. I am new for omron , I want to use CJ2M CPU 34 + CJ1W-SCU32 connect to E5CC temperature controller with RS-485 , I'm no sure it will work or not. Is it possible or not? The manual E5CC No details for SCU32 Sorry I'm not good english. Thank you.
