MVI56E-SMGC ♦ ControlLogix™ Platform
Enhanced FMC722 TPU General Communication Module
Digital Output Data
Digital output data is stored in a controller tag with the following data structure:
Byte Count
4
32
8
8
2
2
4
2
This data is acquired from the server using data blocks 0x1001 and 0x1003 and set by
other devices or the ladder logic. The format of the 0x1001 block is as follows (read
block from the module):
Word Offset
2 to 3
4 to 5
6 to 21
22 to 25
26 to 29
30
31
32 to 33
When the module passes one of these blocks to the ControlLogix processor, the ladder
logic should use the Tag Index value to determine which array index to use for placing
the data into the controller tag database. These blocks are passed to the module from
the server when requested by the client (request data block 0x101) or when the
associated data changes in the server.
