xxx The statuses of bits 31 to 24, 23 to 16, 15 to 8, and 7 to 0 are indicated
in order in decimal notation.
Bit 31 0 1 2 3 4
• The status of each bit indicates the status of each control mode.
Bit 0 status 0: stop, 1: run
Bit 1 status 0: local, 1: remote
Bit 2 status 0: auto, 1: manual
Bit 3 status 0: Not in cascade (cas) control
1: In cascade control
Bit 4 status 0: Not auto tuning (AT)
1: Auto tuning
Bit 31 status 0: Not in program operation, 1: In program operation
• When bit 3 is 1 (in cascade control), the secondary loop of the
cascade can be in any of the statuses auto, manual, or cas. The
primary loop of the cascade is fixed to auto.
Example
When in program operation, auto tuning, in cascade control, auto, remote, and run.
