Automatic control function programming manual ladder language

A configuration change requires moving the card from rack 0, slot 7 to extension rack 1, slot 1.
To avoid having to change the user programme, programme %INI as follows:
%Q073D.B = 0x11
%Q073E.W = 0x1500 (32I/24O card identifier)
REMARK The card identifier must be programmed.
This means that:
- 0x07xx is the logical address
- 0x11xx is the geographic address (physical @).
3.7.4.3 Card Priority %Qrc3C.B
Variables
32I/24O card moved to rack 1, slot 1
Must be programmed in the %INI task. This byte sets the card priority. It is used to associate a card with a systematic
task %TS0, %TS1 to %TS4 or %TS5.
This makes it possible to decrease the systematic processing performed each RTC.
Byte value Processing frequency
0 The card is processed once each RTC
1 The card is processed every 5 RTCs in phase with %TS1
2 The card is processed every 5 RTCs in phase with %TS2
3 The card is processed every 5 RTCs in phase with %TS3
4 The card is processed every 5 RTCs in phase with %TS4
5 The card is processed every 5 RTCs in system task %TS5
The inputs of cards with priority i = 1, 2, 3, 4 are read before the call to %TSi.
The outputs of cards with priority i = 1, 2, 3, 4 are written at the end of %TSi.
If the priority byte is not between 0 and 5, the card is not periodically refreshed by the monitor. It can however be
accessed by explicit read and write functions (see Sec. 10.2, read_i(...)function and 10.3, write_q(...)function).
The system initialises the priority byte with the default value of 0.
