Chapter 10 - Using Remote I/O

DSE contains function blocks, which allow
LINKnet to communicate to SSD
Recommended* Remote IO devices such as
Analog IO and Digital IO as well as other
types of hardware, which use the Modbus
UDP protocol. There are function blocks in
the Block / Remote IO menu: Read Logics,
Write Logics, Read Values and Write
Values. It does not matter where these
hardware devices are located in the Remote
IO rack when reading or writing data to
these blocks. All the blocks care about is
how many Digital modules there are and
how many Analog modules there are.
For example, let's say there are physically 2 Digital Input cards with 16 channels each. To access the 1
Input card, you will use a Read Logics block and set the IP address of the Digital Input card. Logic 1 parameter
refers to the 1
card. Set the First Logic Count to 1. This will access the 1
Now to access the parameters on the 2
function block and set the First Logic Count to 17. This will access the 2

Input card located from left to right. There can be different types of cards in between these Digital Input cards and
it will not affect how these Digital Input blocks are written to, or read from. Now to access this 2
card, use the 2
