LOOP BLOCK
3-48
15 Remote State Input (RSTATE).......................................................................................... CWR
This is an input signal used to remotely change the block state. When state is RUN and
remote state is present, composite state (CSTATE) will take on the value of remote state.
Writable only if local data is configured.
NONE No remote state changes allowed. Composite state is the state value.
RUN 0 Local data for remote state input is RUN.
HOLD 1 Local data for remote state input is HOLD.
OFF 2 Local data for remote state input is OFF.
DEBUG 3 Local data for remote state input is DEBUG.
LSP Input data may be discrete, short or long state source variable. Data must be
valid (0, 1, 2, or 3) or a remote state error will occur.

3.5.4 Loop Block Events
The event codes (and their suggested text messages) for the loop block are given below. See
the referenced database attributes (in brackets) for additional information. See the system
event block for event transition information.
0 BLOCK STATE SET TO RUN.
1 BLOCK STATE SET TO HOLD.
2 BLOCK STATE SET TO OFF.
3 BLOCK STATE SET TO DEBUG.
4 REMOTE STATE INPUT INVALID (5).
