Communicating with Your Module
3-11
The temperature control module generally updates data for single-transfer
on a shorter time period than it updates data for block-transfer.
The module’s period for updating the heat and cool TPO bits it makes
available thru single-transfer is approximately 20ms.
The module’s period for updating the heat and cool TPO bits it makes
available thru block-transfer is approximately 500ms.
The module’s period for updating the temperature values it makes
available thru block-transfer is 1 second.
The module’s period for updating the CV values it makes available thru
block-transfer for heating is set by the heat maximum cycle time you
enter in the configuration block (word 12).
The module’s period for updating the CV values it makes available thru
block-transfer for cooling is set by the cool maximum cycle time you
enter in the configuration block (word 14).
To learn how to configure the temperature control module, read chapter 4.
