I have an SLC 5/03 that Im trying to get the program from. I have a 1747-uic. Im not getting anything to show up in rslinx and I suspect the channel 0 is configured for ASCII because theres an HMI plugged into it. Also the rj45 connection is broken because someone used a crossover ethernet cable...lol. is my best bet to try and fix/replace the 1747-uic? I have an offline copy of a program from a different machine that uses a 'similar' setup and the CH.0 -System is configured for DF1 full duplex,19200,CRC and CH.0 - user is ASCII 19200 baud. Any Ideas? I was using the 3 wire db9 connector running from the HMI to the PLC. I unplugged it from the HMI and used it with the 1747, Should I use a standard DB9 cable with a null modem adapter?

I have a Siemens HMI 6AV2 124-0MC01-0AX0 in my machine. I want to clone the display on the HMI to PC/Laptop. My question is: 1. What software that I need for this task? 2. What kind of interface that I need between the HMI and PC/Laptop (for example ethernet cable, etc)? 3. Do I need to communicate with PLC connected with HMI or can I just connect with the HMI? Thanks in advance for the answer.

Hello I have a wago PLC and i try to communicate to a device through RS485 using the module 750-652. I tried using the WagoAppCom library and came up with this code But i always get errors regarding FB_init block. I though the instance would be automatically matched. I still can't see how to resolve this as Wago library documentation is very poor and contains 0 examples. Has anyone else solved serial comms problems?

I am using OMRON CJ2M-CPU15 with SCU41-V1 communication module I want to establish communication (rs485 modbus) between omron and Schneider device for reading out electrical parameters. How I can do this? I could not find any manuals and this is becoming very hard for me. I want simply to read few registers from Schneider. Where do I set unit number, starting register, ending register, number of data? I was recently using Siemens and Unitronix and started working with Omron recenlty. Do you have any examples or manuals for this? Thanks in advance

HI all, I was trying to connect my compass with PLC via SCU32 RS485 (2 wire ) in protocol macros.[ Unit 1 port2] My send command is " 01 03 00 01 00 03 54 0B' & Expected reply is '01 03 06 XX XX YY YY ZZ ZZ ZZ ZZ" I created a new protocol using CX protocol and created a send message & a receive message command and added to sequence 000. (refer pics) Also added PMCR instrcution in cx programmer (refer pic). I can transmit the data , but i cant see any recieve data in D2000. I am not sure what had done wrong, or am i missing something? Any help is much appreciated!! compass_macro2.psw Compass_TEST.cxp

Please could you assist with the software required to download data tables from 4 off DIRIS A10 Multifunction Meters into TM221CE40R Logic Controller via TMC2SL1 Comms Cartridge using Modbus Protocol over RS485. I have downloaded the Modbus tables from Socomec but not sure how to get these into the PLC. I would really appreciate your help in achieving this. I am using EcoStruxure Machine Expert - Basic to program the PLC & DAQ Factory Developer Release for my Touchscreen. Link to Socomec Modbus tables: https://www.socomec.com/files/live/sites/systemsite/files/SCP/6_gestion_energie/diris/diris_a10/DIRIS-A-10_COMMUNICATION-TABLE_2018-01_DCG01013_MULTI.html#General -
hi 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

Connecting Generic I/O module to Micrologix 1100
Josemarian posted a topic in Allen Bradley / Rockwell Automation
Hello All, Am a bit new to practical PLC applications. I was trying to configure a Phoenix Contact I/O module (1452916) on a MicroLogix 1100 PLC but it kept faulting out with the fault light RED. It would say "Major Error Halt S:1/13". The error description says I/O mismatch. The error code is 187h (see attachment). The Phoenix module has a cable with 19 pin positions for the 8 input. I connected the pin 17 and 18 to 24 volts and 0 volts respectively. Then because I was using input 5 I connected the pink wire to PLC input (I/1) 24volts and the White/Yellow wire to the PLC common. On the I/O configuration on RSLogix 500, I used "Other" ( See attachment) but did not know the vendor details. Could anyone help me with the steps on how to communicate with the module? I have also attached the PLC program I was running. Thanks -
Hello, I have been so many days trying to comunicate the multiway software trought a serial usb converter with the SCU31 device, using a omron function block to read a holding register, but I can't achieved it. Now Im receiving some frames on multiway, but there is always some errors. I was wondering if somebody in here that have worked previously with modbus and omron can be able to help me in how to configure everything corectly to be able to read the value from multiway, on the plc, and where is this value saved. I'll upload some captures to show what I have done till now.

Genst, Could You please advise how can I connect to CJ1M CPU12 - shown in attached picture. DB9 port is used for communication with remote input/outpus rack. There is this small portabove DB9, but first I don't know what cable should I use and seconde I don't know if it is possible to usi this port when PLC talks on DB9 with remote input/output rack. I want to connect to CX-programmer to be able to online troubleshoot PLc program. thanks in advance. tomasz

Hi guys, I'm trying to communicate with a scale controller (Rice Lake ACT20-AN) to read gross weight. Scale controller: RS485, ASCII bidirectional protocol, Baud 9600, Address 1, Delay 0, Parity None, Stop 1 PLC: Channel 1, Data Bit 7 (unclear if it should be 7/8), Parity None, Stop 1, Sum check code Exist, 9600bps, Non procedural protocol (should this be bidirectional?), Station number 2 (should this be different than scale?) I am using $Movp "$01t75CR" D6050, Movp K1 D6000, Movp K4 D6002, G.Output U8 D6000 D6050 M7000 which seems to work okay since M7001 does not turn on? I do not get any data, however, when running Movp K1 D6100, Movp k7 D6102, G.Input U8 D6100 D6150 M7100 at the same time as the G.Output instruction. I have attached the PLC program. Also, for wiring I wired the RS485+ to SDB and RDB, then RS485- to SDA and RDA as suggested by the scale controller manual. I then grounded the cable shielding along with SG and both FG connections. Any help would be appreciated in figuring this out, thank you! Scale_111219.gxw

Dear All. i'm a new user for Janitza. and i have issue related to RS485 actually, not to Janitza itself. i have one device (UMG 96RM), where there is only RS485 (2 pin only), no RS232, no USB, No Ethernet port. i'm trying simply to connect the device to the PC, via (USB to RS485) convertor, but i'm not able to do it. for me, this is the first time i'm see (RS485 2 Pins), usually there is Ground signal also. anyway, could you please somebody help how to connect? shall i add a pull up & pull down resistors at the device? and what is the power supply i must use? noting that, i tried many things, but still nothing happened. Appreciate if somebody can help Best regards.

Hi I'm trying to figure out how to use the OP320-A to control the relays on the FX1N-20MR. I have mastered the OP edit tool, but I havn't learnt how to use GX Developer. The FX3U and op320 by 485 setting youtube is a good start. Does anyone have a GX Developer project file available. Is there an OP320 and FX1N or similar that comes together, pre-programmed, ready to use. I know how to write C++ programs to send RS485 commands, but this GX developer looks complicated. many thanks Tim

Hello Ladies and Gents, Im quite new to working with Omron. I am struggling very much to get online with an Omron CPM2C-S110C. It has a CIF01 card also. I hear this PLC is quite an old one. I have referenced the manual on 'connecting a computer running support software' and double checked I have the correct cables. The ones I am using and the way I am connecting is:- PLC Peripheral slot >> CS1W-CN118 >> XW2Z-200S-CV >> serial to USB >> Laptop Checking on Device Manager, I have all the drivers installed, the comms ports are correctly numbered yet I still cannot connect. There are 4 dip switches on the top right hand side of the CPU and all are swiched off. I have called Omron Tech Support and they said to ignore them in this instance. The RS232C port on the CIF01 is used by a barcode scanner so there is no means to connect through that (I have been told) I feel that I have been through setting and checked in CX-Programmer and nothing looks obscure. Please offer me any ideas you may have. I would greatly appreciate it. Thank you.
