SAIA PLC - Modbus TCP truncates 32 bit value
Lupin_III posted a topic in Other PLCsHI, I'm reading values from an SBC SAIA PLC ( PCD2.M5540 model). My problem is that some values are 32 bit, while modbus return 16 bit values, of course. Registers are consecutive, so I cannot read for example 9008 and 9009 since they store 2 different information.To make it clearer I attach the PLC watch window. As you can see R9009 is a 32 bit value, but I can't require R9009 and R9010 via modbus since in R9010 register there is a different information. AS well as in R9008. Speaking with SAIA technical support, they explain me that their PLC registers are natively 32 bit, so in order to read them I need a 32bit modbus client. I cannot find anything like this, neither I can use standard modbus, since the buffer I get back is a 16 bit for each register. So 16bit for R9008, 16bit for R9009, 16 bit for R9010. What I can do?Thanks
User login in PG5 Web Editor 8
nygma posted a topic in Other PLCsI am using PG5 v2.1.310 and Web Editor 8. I am trying to implement user access on my project. I have created a login page, made it as the default page, put the logon component on the page and also added a user to the project. The page loads without any issues, but nothing happens when I enter the username and password. I read the help, and I don't think I have missed anything. Any ideas? Thanks, Csongor
