Hi guys,

I am a little bit confused. 

I am using FB915 function MB_PNHCL for my redundant Modbus on CPU port.

As I see, I can configure 8 request in parameter DB, each consists Modbus function, DB when data will be storage, start address and end address of Modbus register.

Then, I have found that I can use also Job_List function to create request where parameters are Modbus function, start address and length of my request.

My question is where the data of Job_List requests are stored. Is this related in any way with request in parameter DB or it's separated?

Well, now it's much more clear for me.

So, at the end my jobs should match my DB declaration inside my parameter DB.

What if I create a job wihich doesn't mach? The telegram will be read but not stored in any DB?
