1734-232ASC, 1734-485ASC, 1738-232ASCM12, 1738-485ASCM12
Although the RS232 and RS485 modules can produce up to 132 bytes of data,
only a message of 24 bytes can be consumed by the DeviceLogix module.
The data from these modules can be addressed in the DeviceLogix program
using either bit or word tags.
