Actions of the FVP110 During Operation

Block Modes

All function blocks have modes. All blocks have their mode, expressed by the MODE_BLK
parameter. It is a structure of four components:
Target
Actual
Permitted
Normal
Table 26 shows the modes supported by each FVP110 function block. Modes marked with
( ) cannot be specified as target.
Function Block
Resource
Transducer
AO
DI
OS
AR
IS
PID and PID2
This is the mode into which an operator wants to bring this block and is writ-
able.
This mode shows the actual mode of the block and is read-only. When nec-
essary conditions are satisfied, this mode becomes same as target. There is
a chance that actual mode says different from target by some reason.
This mode shows which mode is allowed in the function block.
This mode is a memo to record mode what an operator expects in normal
conditions.
