Hi,
I got two questios:
There are two slave devices(SEL-787) from which I should read data via MODBUS RTU.
I checked SEL-787 manual and it says it supports EIA -232 , but my collegue order
"
6S7 341-1CH00-0AE0
Communication processor with connection: RS422/485 (RK512, ASCII, 3964(R), loadable driver)
"
Should we change order to:
"
6ES7 340-1AH02-0AE0
Communication processor with connection: RS232C (ASCII, 3964R, printer); V1.0
"
