Thank you all for the advices. After a bit struggle I succeded For the ID, I put 2 and it was OK, the tricky was for the DWORD bzte order, default is Big-Endian and it should be Little-Endian. @Fernando Castro thank you for the advice to try with MI, after that I figured out that comm is ok and that I have problem with adressing.

Yes

Thank you Fernando, I already tried 5112, 5112, 5113 type Int, Dint but Scada indicate that there is no communication. In the moment my problem is because I dont have comm and with finding the right value I belive will not be problem... Regards

Thank you Fernando. I will check with socket connection. Regarding adressing, Vision 280 should be basic model so adressess listed in manual should be Decimal, for advanced is Hex. Anyway I will try. Thank you one more time.

Hello all, I have question related to connecting Vision 280 with Modbus TCP zenon SCADA driver. I have experience with other PLC-s but not with Unitronics. Please find attached config below: Below you can see zenon driver config and one variable config. I tried to see ML12 from program. Is this the way to directly call adress from SCADA or I missed some step? sigma is PLC name, PLC IP is in range of PLC.

Thank you all so much. I just tried with new Serial port to USB converter and it is working. Old converter is working with other serial devices with same configuration. Strange but happy to be able to connect finally.

Yes, I can enter in INFO mode. There I see that PLC is in RUNNING state (Tried to stop it also). Also cheched Comm parameters there. There I found in Model & OS menu: Vision2xx O/S, v5.04 (B64) HW: A and below state RUNNING Regarding setup of the adapter in Device manager all is same as in the PLC and of course port is appropriate, with the wrong port message code is 207 and it is immediate, in my case I see on the converter LED that Tx signal is active but there is no reponse from the plc and on the end Timeout Err occurs. I see in System Mode option "Init", should I try to initialize PLC? I suppose there is nothing bad to do it on brand new plc without any app on it. Thanks

Yes, I already tried all with Port 2 as well.

All looks OK for me, cable is new and delivered from Unitronics, anzway problem existed with cable I made according instructions from manual. Can some Software version be a problem? Thank you

@AlexUT Thank you for the answer. Tried but it is the same. First I tried to make my own cable with RJ11 port but now have brand new from the supplier so this should be ok. When I hold "i" button on the panel, enter in Settings menu, I see that parameters of the Port 1 are 57600, 8, None, 1. After your message I tried to change it on 7, E, 1 (on my laptop and config of the connection in VisiLogic as well) but no solution... Any other suggestion? Thank you one more time

Hello all, I have brand new Vision 280 FW Version 5.04 and Visi Logic 9.8.96 (Yes, it is quite old plc FW but I have to connect on it with SCADA to take some data for the central visualisation). This is spare plc for the one installed on the line and I have to acces to it. Now I am trying to connect on the new plc without application on it using Port1 (RS232) , cable MJ10-22-CS25 and USB-Serial converter which I am using a long time so I dont expect problem there. All comm parameters should be set well (57600, 8, None, 1), on the plc is same. When I go on CONNECTION -> Communication & OS - > Get PLC Information, I have message > "Communication Driver Error (206) " As i am new in Unitronics, can someone give me advice what to do? Tried to find older version of the Visi logic (5 OR 6) but there is no on site and wrote on support email last week but nobody answered. Thank you in advance.

Thank you all for the support. I found issue. On one encoder problem was wiring and another encoder is broken. regarding configuration all is as it is described and as I already done.

@kratmel @Rivka Thank you so much for the answer. Last few days I was not near machine so I am able to test it now. My first setup was as @kratmel suggested, I also tried with High speed type: Measure Length (Pulse Counter) and A/B interface of course. I have 2 encoders and in both cases during movement value of the tag UIS-WCB2_0.B1: Counter is alternately changing from 0 to 1. When I stop movement last value remains. During movement value of the tag UIS-WCB2_0.B1: Frequency is 0. I need this encoder for position reading so I would like to have some number which I can calculate position from.

Can anyone help me how to use UIS-WCB2 for the position detection? I have connected Encoder A and B outputs on card inputs, it counting But I need two directional counting and can't figure out how to set it. I am new with Unitronics so please feel free to propose obvious simple solutions if exist. Thank you in advance
