MSR control byte values
A selection of MSR control byte values has been created for CICS® and stored in the copybook DFHMSRCA. The following table shows you the meaning of each bit.
The constants supplied in DFHMSRCA are listed in Table 1.
| Constant | Meaning |
|---|---|
| DFHMSRST | MSR reset. All lights and buzzers off. MSR available for input. |
| DFHMSCON | Transaction ready for more input. Green and yellow on; emit short buzz; IN PROCESS (user) mode set. |
| DFHMSFIN | Input complete. Green on; emit short buzz; IN PROCESS mode reset. |
| DFHMSALR | Operator alert. Green, yellow, and red on; emit long buzz; IN PROCESS mode reset. |
| DFHMSALS | Operator alert. Green, yellow, and red on; emit long buzz; IN PROCESS mode set. |
| DFHMSIPY | IN PROCESS state set. Yellow on. |
| DFHMSIPN | IN PROCESS state reset. |
| DFHMSLKY | MSR operation inhibited. Yellow on. |
| DFHMSLKN | MSR input allowed. Green on. Yellow on. |
| DFHMSAEY | MSR autoenter on. Yellow on. |
| DFHMSAEN | MSR autoenter off. Yellow on. |
| DFHMSLBN | Long buzzer suppressed. Yellow on. |
| DFHMSLBY | Long buzzer permitted. Yellow on. |
| DFHMSSBN | Short buzzer suppressed. Yellow on. |
| DFHMSSBY | Short buzzer permitted. Yellow on. |
| DFHMSNOP | Leave all MSR settings unchanged. |
STATE MASK
If a bit is on in the STATE MASK byte, the state it represents is adopted by the device if the corresponding bit is also on in the STATE VALUE byte.
- 0 USER
- User mode. Turn on the yellow light if the same bit is on in STATE VALUE.
- 1 LOCK
- Locked/Unlocked. If locked, MSR input is inhibited.
- 2 AUTO
- Autoenter on/off. If set on, any card read by the MSR causes an ENTER operation. If off, only a secure card causes an ENTER.
- 3 Ai1S
- Suppress audible alarm 1.
- 4 Ai2S
- Suppress audible alarm 2.
STATE VALUE
Modifies state to on or off if the corresponding bit is set on in STATE MASK.
INDICATOR MASK
Performs a similar function to STATE MASK, but for indicators.
- 0
- Light 1 (Green)
- 1
- Light 1 (Green)
- 2
- Light2 (Yellow)
- 3
- Audible alarm 1 (Long buzz)
- 4
- Audible alarm 2 (Short buzz)
INDICATOR VALUE
Performs a similar function to STATE VALUE.
