7. I/O Module DIT Register Reference
This section describes the I/O Data Spaces allocated in the Data Interchange Table for each I/O
Module that can be used with the P3 range of CPU’s.
This DIT Register reference can be used when configuring supervisory systems to access I/O from
the P3 CPU, or for configuring I/O modules programmatically.
The DIT register addressing given in this section is always based from 0. This is an address
“offset” from the start of the relevant Data Space (see Section 6.6 for more information on I/O Data
Spaces). The actual DIT address depends upon the I/O Slot in which the module is installed. To
find the actual address, add the DIT offset defined in this section to the DIT Start Address for the
relevant section found in Table 6.2: DIT Address Map of the Expander Rack through to

7.1 M1101A
–24VDC/12V Solar 3A Charger/Power Supply
DIGITAL INPUT DATA SPACE
DIT (Offset)
Digital Inputs
where individual inputs are allocated as follows:
0
Bit 0 (LSB) = First Scan
Bit 1 = Primary Supply Status (1= Program in First Scan)
Bit 2 = Temperature Sensor Status (1 = Sensor is connected)
Bit 3 = Battery Level Warning (1 = Battery Level Low Warning Alarm)
Bit 4 = Battery Level Critical (1 = Battery Level Low Critical Alarm)
Bits 5 to 16 will read as 0
ANALOGUE INPUT DATA SPACE
DIT (Offset)
Battery Voltage (in Volts x 0.1)
0
Digital and Analogue Output Data Spaces are unused by this module
CONFIGURATION DATA SPACE
DIT (Offset)
Critical Battery Level (in Volts x 0.1)
0
Alarm Battery Level (in Volts x 0.1)
1
Battery Test Interval (in minutes)

7.2 M1102B
– DC L - 24Vdc Logic Power Supply
No Data Spaces are used by this module
This module has no data readable in the DIT.
When this module is allocated in an IEC61131 program, then a single digital input is available
to the program that will energise on the first scan of the program.
7.3 M1104A
– DC LF - 48Vdc Logic/Field Power Supply
No Data Spaces are used by this module
This module has no data readable in the DIT.
