Current/Voltage Analog Output Module Features (5069-OF4, 5069-OF8) Chapter 5
Channel Offset
The Channel Offset feature compensates for any known error on the sensor or
channel to which the sensor is connected. The value is set in signal units and is
added to the output data.
For example, consider an application that uses the Current (mA) input type with
the 4…20 mA range and scaling at 0…100%. If a channel used in the output range
4…20 mA has an error that results in it consistently reporting 8 mA as 7.8 mA,
you must account for the error by setting the Channel Offset to 1.25.
To see where to set the channel offset, see the following:

• 5069-OF8 module, see
page 105
Hold for Initialization
Hold for Initialization causes outputs to hold present state until the value
commanded by the controller matches the value at the output screw terminal
within 0.1% of full scale, providing a bumpless transfer.
If Hold for Initialization is selected, outputs hold if there is an occurrence of any
of these three conditions:
• Initial connection is established after power-up.
• A new connection is established after a communication fault occurs.
• There is a transition to Run mode from Program state.
• The module loses SA power. In this case, the data echo value goes to 0.0.
The I.Ch[x].InHold tag for a channel indicates that the channel is holding.
To see where to enable Hold for Initialization, see the following:
