Exchanging Data with a Loop Control Unit at Other Node
You can select the following two modes for exchanging data with a Loop
Control Unit at another node via the Controller Link.
1) To use part of the regular Data Link (use the CPU Unit Terminal
block or Expanded CPU Unit Terminal block)
Use this mode when exchanging data with a PC (CPU Unit) at another node
or when exchanging data with a Loop Control Unit at the other node PC.
Note
The maximum number of points must be within the “number of points used by
the CPU Unit Terminal (maximum number of function blocks 16, 128 contacts
per function block, analog value eight words) + number of points used by the
Expanded CPU Unit Terminal block (maximum number of function blocks 30,
64 contacts per function block, analog value 64 words)”.
The regular Controller Link Data Link with the PC at the other node is
established on the PC on which the Loop Control Unit is mounted. On this
Data Link, the Loop Control Unit reads and writes the analog signals or
contact signals to part of the Data Link on the CPU Unit by the CPU Unit
Terminal block or Expanded CPU Unit Terminal block. Reading and writing in
