Communicate with a PanelView™ Standard Terminal 9-13
Plan and Configure Explicit
Server Tags
Server Tags
Explicit server tags are similar to I/O tags except that the controller
initiates the communication with the terminal. Explicit server tags do
not show up on the input and output maps of the scanner.

Read Tag
Write Tag
A PanelView terminal gives you 14 assembly
instances (3 to 16) for explicit server tags.
Tag address = I:0
If a bit-level tag, then tag
address = I:0/bit # (0 - 15)
If a bit-level tag, then tag
address = I:0/bit # (0 - 15)
Tag address = O:0
If a bit-level tag, then tag
address = O:0/bit # (0 - 15)
If a bit-level tag, then tag
address = O:0/bit # (0 - 15)
Each instance give you 64 words for
either input or output data.
Write Tag
Use an assembly instance for either
input (write) or output (read) tags, but
not both.
