Circuit monitor registers 1728–1744 are conditional energy registers.
Conditional energy can be controlled in one of two ways:
• Over the communications link, by writing commands to the circuit
monitor’s command interface, or
• By a digital input—for example, conditional energy accumulates when the
assigned digital input is on, but does not accumulate when the digital input
is off.
The following procedures tell how to set up conditional energy for command
interface control, and for digital input control. The procedures refer to register
numbers and command codes. For a listing of circuit monitor registers,
see Appendix A—Abbreviated Register Listing on page 127. For a listing
of command codes, see Table B– 2 on page 183 in this chapter.
Set Control—To
set control
of conditional energy to the command interface:
1. Write command code 9020 to register 8000.
2. In register 3227, set bit 6 to 1 (preserve other bits that are ON).
3. Write 1 to register 8001.
4. Write command code 9021 to register 8000.
Start— To
start
conditional energy accumulation, write command code 6321
to register 8000.
Verify Setup—To
verify proper setup
, read register 1794. The register
should read 1, indicating conditional energy accumulation is ON.
Stop—To
stop
conditional energy accumulation, write command code 6320
to register 8000.
Clear—To
clear
all conditional energy registers (1728-1747), write command
code 6212 to register 8000.
Set Control—To configure conditional energy for digital input control:
1. Write command code 9020 to register 8000.
2. In register 3227, set bit 6 to 0 (preserve other bits that are ON).
3. Configure the digital input that will drive conditional energy accumulation.
For the appropriate digital input, write 3 to the
Base +9
register. See the
digital input templates in Table A–4onpage166in Appendix A—
Abbreviated Register Listing.
4. Write 1 to register 8001.
5. Write command code 9021 to register 8000.
Clear—To clear all conditional energy registers (1728–1747), write
command code 6212 to register 8000.
Verify Setup—To
verify proper setup
, read register 1794. The register
should read 0 when the digital input is off, indicating that conditional energy
accumulation is off. The register should read 1 when conditional energy
accumulation is on.
