Centipede 2® Module™ Temperature Control System
Appendix C: OI Settings Setup: wr:10,"Value"
Register 10 of the Operator Interface is the “Settings” register. The Register consists of 16
bits and the register is defined below. The “Value” is the Decimal equivalent to the Binary
for the 16 bits.
Register 10 – Operator Interface Settings Register
Bits 15-0
Cs: Controller Settings
0:
ALARM RELAY CTRL – Actuate/de-actuate (1/0) relay when alarm active
1:
LOW TEMP LATCH – Set to enable latch of low temperature alarm
2:
HIGH TEMP LATCH – Set to enable latch of high temperature alarm
3:
OPEN RTD LATCH – Set to enable latch of open rtd alarm
4:
SHORT RTD LATCH – Set to enable latch of short rtd alarm
5:
NOT USED
6:
NOT USED
7:
PASSWORD ENABLE – Set to enable GUI password
8:
TIMER DISPLAY 12 HOURS – Display timer (GUI) in 12 hour mode (AM/PM)
9:
TEXT UI SESSION TIMEOUT DISABLE – Disables text ui session timeouts
14:
ALARM LOG CLEAR – Clear alarm history one-shot when set
15:
UNLATCH ALL ON-SHOT – Set to do a single unlatch of all latched alarms
Example “Value” determination*:
In the above example Cs9 (Bit Pos. 9) is set to 1. This is translated to a decimal value as 1
* 2 ^ 9. And similarly Cs0 (Bit Pos.0) is set to 1. This is translated to a decimal value as 1
* 2 ^ 0. Other bits, such as Cs2 (Bit Pos. 2), as set to 0. This is translated to a decimal
value as 0 * 2 ^ 2. The sum of all of the decimal values is the final decimal number to use
for the command.
BH> wr:10,513
This command places the Operator Interface Register 10 bits such that Cs9 (Bit Pos. 9)
and Cs0 (Bit Pos. 0) are activated. All other bits are inactivated.
*Note: Microsoft Windows Operating Systems have a simple Calculator as part of their
suite of Accessories. That Calculator software includes a View -> Programmer setting,
where one can easily convert from binary to decimal and reverse.
