feedback of each temperature, output setting, and channel status is returned to the PLC in the %I<br />

and %AI data.<br />

The %Q data sent to the TCM is used for quick control of each of the eight output channels. In<br />

contrast, parameter data is sent to the TCM using groups of %AQ data to reduce the demand on<br />

the PLC I/O services. Full feedback of the TCM temperatures, outputs, and status is provided<br />

every PLC sweep for minimum system delays.<br />

To use the TCM, configure it as a Foreign module, with the default ID of 3, using the Logicmaster<br />

Configuration software. The module is assigned to a particular slot and rack like any other PLC<br />

module. The data transfer sizes are set to 64 %I, 28 %AI, 24 %Q, and 3 %AQ words of data<br />

communicated between the PLC and the TCM.<br />
