IO Image Table Configuration
The PLC programmer will have to configure the PLC master so that its IO
image table matches that of the slave. The module is from the PLC
reference point. The slave is configured at the factory to have the following
16 IO modules:
Table 1 IO Modules
IO Module No. Module Type Size (Bytes) Descriptions Notes
1 Output 12 Broadcast Message Data A
2 Output 2 Multicast Message Data
3 Output 12 Data Table 5 to KV and Flow (Pump) B
4 Output 1 Gun Bank/Page No. from PLC
5 Output 4 % Flow Trim Adjust B
6 Output 1 Heartbeat from PLC
7 Output 12 General Unicast Message
8 Output 64 Goto Preset Value (for each gun) C
9 Output 2 Paged Gun General Information
10 Input 12 Paged Gun A Monitored Data/Status
11 Input 12 Paged Gun B Monitored Data/Status
12 Input 12 Paged Gun C Monitored Data/Status
13 Input 12 Paged Gun D Monitored Data/Status
14 Input 8 Global Status and Fault Info
15 Input 1 Heartbeat from Gateway/Slaves
16 Input 8 Paged Gun General Information (4 guns)
NOTE A: The last 3 bytes are never used.
B: The last byte is never used.
C: 1 byte for each of the maximum number of guns which may be used in a system. Since there is a
maximum of 32 guns in the system, the last 32 bytes are not used.
The details of these IO modules are covered in the following sections.
IO Image Table − Module Definitions
Each IO module serves a specific purpose in transferring data either to or
from a gun control node. The terms output and input image tables are
referenced from the perspective of the PLC. The following tables describe
the contents of the IO image tables.
