Data Point Table
The iMAC2
Controller’s data point table consists of 1617 16-bit registers. The registers contained within the
address range 0-1535 are accessible via both the serial communications port and the Ethernet
communications port. Registers in the address range 1536-1697 are accessible via the Ethernet
communications port only.
The register map is arranged as follows:
Figure 6.6: iMAC2
Controller’s Data Point Table
Each iMAC2 Controller has an allowance for up to 255 16-bit data registers to be utilised by iMAC fieldbus
modules. Each data register has an associated status register, resistance register, and error register.
iMAC I/O modules need to be configured with an iMAC address in the range of 1 to 255. The iMAC address
maps directly to the corresponding Controller data register. The corresponding addresses of the status
register, resistance register, and error register are +256, +512 and +768 offset respectively.
For example, consider a single address input module (e.g. DI4 module) that is programmed to fieldbus
Address 5, the data register in the iMAC2 Controller
’s data point table will be Address 5. The associated
status register will be at Address 261 (5+256), the associated resistance register will be at Address 517
(5+512) and the associated error register will be at Address 773 (5+768).
For a complete range of data definitions, including system runtime variables, refer to the IMACB153 iMAC
Controller Serial Communications Manual, or the IMACB2010 iMAC2 Controller Ethernet Communications
Manual.
