Module Properties dialog box - Ch0x page parameters (5094-OF4IHS, 5094-OF4IHSXT)
The
Ch0x
page (5094-OF4IHS, 5094-OF4IHSXT) includes the following parameters:Parameter | Description |
Disable Channel | Select to disable channel configuration or clear to enable channel configuration. Disable the channel to help prevent erroneous fault reporting, such as open wire fault, and to help prevent the FLT LED for that channel from illuminating. |
Output Type | The output type for the channel. |
Output Range | The output range for the output type. |
Enable HART | Select to enable communication with HART devices. |
Channel Offset | To compensate for any error in actuator operation, the module allows an offset to be added to the output channel value sent from the controller. Values are entered in Engineering Units (EU). The default value for the channel offset is 0.0. |
Hold for Initialization | Select to cause the physical output to hold its present state until the value commanded by the controller matches the value at the output screw terminal within 0.1% of full scale. This feature prevents spiking of the output when transitioning into Run mode from Program mode, when recovering from a fault state, or at power up. |
Off | Select to turn off the output channel. |
Hold Last State | Select to cause the output to remain at the last value sent from the controller prior to being placed in Program mode and Communication Fault mode. |
Engineering Units | Enter the unit of measure used for the channel. |
High Signal | Enter one of four points used in scaling. The high signal is in terms of the channel signal units and corresponds to the high engineering term when scaled. The scaling equation is used. High Signal values must be greater than Low Signal values. |
High Engineering | Enter one of four points used in scaling. The high engineering helps determines the engineering units the signal values scale into. The high engineering term corresponds to the high signal value. The scaling equation is used. |
Low Signal | Enter one of four points used in scaling. The low signal is in terms of the channel signal units and corresponds to the low engineering term when scaled. The scaling equation is used. |
Low Engineering | Enter one of four points used in scaling. The low engineering helps determines the engineering units the signal values scale into. The low engineering term corresponds to the low signal value. The scaling equation is used. |
Diagnostics | Select to open the Ch0x Diagnostics dialog box and view diagnostic information. |
