Figure 6.1 - I/O DIT Address Map for T2 CPU
Notes:
1. 16 registers are allocated for each analogue I/O Slot. Each analogue value is stored as a 16
bit number. The scale of this value is dependent upon the type of I/O module being read, and
it configuration.
2. Digital I/O is packed into two DIT registers per I/O Slot, with each Digital value representing 1
bit.
3. When a module is installed into the system, it will be detected by the CPU in seconds and
then automatically scanned according to its module type. No special configuration is required
for this to occur.
4. Digital Modules are scanned every 10ms.
5. Analogue Modules are scan rate = (10.n + 10) milliseconds, where n is the number of
analogue modules installed on the Master and Expander Bases. Eg 3 installed analogue
modules will be scanned every 40ms, 15 Ananlogue modules will be scanned every 160ms.
