5.5 Function Blocks Setting
This section describes the procedure taken to set and
change the parameters for each block. Obtaining access
to each parameter differs depending on the configura-
tion system used. For detail, refer to Chapter 4 for each
configuration system.
Block mode consists of the following four modes that
are controlled by the universal parameter that displays
the running condition of each block.
- TARGET_MODE: Sets the operating condition of the
block.
- Actual: Indicates the current operating condition.
- Permit: Indicates the operating condition that the
block is allowed to take.
- Normal: Indicates the operating condition that the
block will usually take.
Table 5.5.1 shows the operating conditions which the
individual blocks will take.
