  1. Hi, Now I’m doing that program, but I’m not sure is that program now right. I download that program and tried to read I/O data with SCADA , but that is not right data. I connected some inputs, but when I read them, they will change 0 and 1. They must be solid 1. I need to move all 8 digital inputs. I attached my program with that message. Could you help me with this, please? BR Antsu Modbus.U90
  2. I have got only one PLC and I will use RS232 with MJ20-PRG module. When I change serial port settings for MODBUS, can I get connection to PLC by chancing cable to different PC if I will change program? Are MODBUS and U90Ladder-program settings same?
  3. I have in use SCADA software to which I would like to move the I / O data from Jazz JZ10-11-R16 PLC in through Modbus with MJ20-PRG port. I try to examining of the manual how to do it, but the configuration seems a bit confusing. Is it in this case of Jazz serial port need to make settings under (page 253) manual? And settings to Modbus like page 294 and page 296 Modbus parameterization? I would like to I / O data to be available always, so how the parameters of executing must be carried out? On page 296 is an example, where is connected EN input to SB41. Could it be, for example SB2? Can you connect to PLC (for programming) when, the COM settings are changed? On page 299 is an example where SCADA is a Modbus master. In my case, I would like to read all eight inputs. Is it configured: SI141 = 1, SI142= 34 001, SI143 = 8. How about SI144 and SI145? What if I want to write outputs? Does the SCADA write to a memory and connect output to it? BR Antsu
