Sourav Sau Posted October 18, 2017 Report Posted October 18, 2017 I am trying to program a CJ2M-CPU11 model. I have one input module CJ1W-ID262 and 4 output module OF CJ1W-OD212. I am trying to do a basic one line program with i/p address 0.00 and output address 4.00. But after transfer it to plc one error massage is coming. When I checked the error log it was showing i/o settings error. Could you please tell anyone where was my mistake..Please Help...
innoaloe Posted October 18, 2017 Report Posted October 18, 2017 Go look for IO Table Settings. You need to set it properly. Basically it's to register your ID262 and OD212 so the CPU can identifies the units prior to mapping the I/O address. 1
Sourav Sau Posted October 18, 2017 Author Report Posted October 18, 2017 Thank you Mr. Innoaloe... I set this up. And error problem solved. Thanks a lot.
Sourav Sau Posted October 18, 2017 Author Report Posted October 18, 2017 Can you please explain the connection of input terminal of ID262. A1,A2,A3,A4...A20 and B1,B2,B3....B20.. Where to give -ve and where +ve?
gtsuport Posted October 18, 2017 Report Posted October 18, 2017 Please see the attached information. The complete specification and additional information can be located in the W393 manual.
Sourav Sau Posted October 19, 2017 Author Report Posted October 19, 2017 Dear All thanks for helping me.. Actually I am beginner with a little knowledge. So please help me. Another Multi function meter(7KM-PAC 3200) is there. I need to communicate with the MFM and to program in Cx programmer. Please give me some suggestion how to do it. If any video or any file then please send me in my mail id- sourav.sau91@gmail.com. This PLC did not have any Ethernet port and MFM has a ethernet port. So please suggest for communication and also programming and scaling of that MFM meter through PLC.

So please suggest for communication and also programming and scaling of that MFM meter through PLC. I checked the 7KM datasheet, and it is equipped with ModbusTCP function. In order to communicate you have to buy an Ethernet Slot CJ1W-ETN21, otherwise you cannot communicate to that meter. Omron also provide ModbusTCP Function Blocks that can be used together with the CJ1W-ETN21 to make programming easier. Regarding how to, since you're in India it should be easier if you contact Omron reps in India. They got 3 main offices in Delhi, Mumbai, and Bangalore. I don't know where you are, but local contact should be easier nontheless.
Sourav Sau Posted October 19, 2017 Author Report Posted October 19, 2017 As you told I just now discussed with omron service provider in Coimbatore. They will provide Ethernet system in PLC to communicate with that MFM. After that I will again discuss if any problem is there in programming part.
Sourav Sau Posted October 23, 2017 Author Report Posted October 23, 2017 (edited) Sir, I connected my Omron HMI(NB7W-TW01B) to plc and I am trying to create a number display which will show the PAC3200 voltage value in the HMI. But I could not understand what the address I will give in HMI so that it will show the value of voltage from MFM (PAC3200) to HMI. And I am using a RJ45 Ethernet port in PAC3200 and also in HMI. Please tell me the process how I will put the address and where I will get the address for different parameter like voltage, Current, Power Factor ... etc. Edited October 23, 2017 by Sourav Sau
Crossbow Posted October 25, 2017 Report Posted October 25, 2017 We don't know the address, there isn't one. It depends on the program you write to read the data from the external device and where you write that data to. When you write the Ethernet communication to talk to the meter, you will code where the data gets placed in the PLC's memory.
Sourav Sau Posted October 28, 2017 Author Report Posted October 28, 2017 That means Sir, for MFM and HMI communication PLC must need? If so then then what is the instruction in Cx-Programmer that will code data from MFM? could you please help me regarding this?
Crossbow Posted October 31, 2017 Report Posted October 31, 2017 You need to know where the data exists in that meter. The manufacturer should be able to provide you that information. When you write the custom code to perform the communication from the PLC side, you will decide where that data goes in the PLC memory. There is no default, you have to code it.

ModbusTCP with NB HMI uses the []X addressing, example 4X Addresses is to read Holding Register values. Which Holding Register you should read again? You must look onto the MFM Communication Manual. NB can only help you to read and view it, but it wouldn't know which register it should read if you don't specify it. Since your MFM have ModbusTCP Server built-in, you shouldn't need any PLC for this communication.
