TPO period (ms): Time Proportioned Outputs (TPO) are outputs that turn on and off in proportion to an analog value.
Typically, the output will turn on and off once during the specified TPO period (cycle time).
Specify a cycle time for all enabled TPO outputs in the module. The range of the cycle time is 20ms to 10 minutes
(600,000ms). Each TPO will pulse ON and OFF once during each cycle period, unless a minimum OFF/ON time is speci‐
fied. The default TPO period value is 1000ms.
Min OFF/ON (ms): Specify a minimum OFF/ON time (shortest allowable ON or OFF pulse) if the output devices are not
capable of changing stat withing 1/32767 of the desired time. (Mechanical relays are an example of such a device).
The range for the minimum OFF/ON time is 10ms to 10 minutes. All settings will maintain the time proportion by wait‐
ing multiple cycle times, if needed, to turn an output ON or OFF. The default value for this field is 100ms.
Channel: A channel is a physical IO point that can be either analog or digital.
Modbus Address: Configuration must be sequential. Addresses are fixed sequentially from the base address.
Mode: This option will enable/disable the discrete output channel.
TPO: Select the Enable Time Proportioned Outputs (TPO Disabled/Enabled) in the dropdown list, if it is desirable to
have any discrete outputs in this module function as time proportioned outputs. All discrete ouputs support this TPO
capability. Each channel can function as a TPO output or a discrete output, but not both. If TPO is enabled, the TPO
period, Min. OFF/ON and TPO IODB/Modbus address must be configured as well.
The analog value associated with each channel will control how long the TPO will be ON or OFF (16‐bit value from 0‐
32767). For example, an analog value of zero will tell the output to be OFF. A value of 3276 (10% of 32767) will turn the
output on for 10%of the “TPO Period” value. 32767 (full scale) will control the output to be ON at all times except for
Min OFF/ON time.
TPO Modbus Address: This field indicates the register addresses of the analog outputs that control the TPO’s when
enabled. Configuration must be sequential. Addresses are fixed sequentially from the base address.
