Chapter 3 Hardware Specifications and Considerations
All 1756-IF6CIS channels are supplying loop power
If all RTB VOUT-x terminals are used and all RTB RTN-x terminals are
unused then all channels of the IF6CIS are supplying loop power, and there is
no additional work required.
One or more 1756-IF6CIS channels use external loop supply
If one or more RTB VOUT-x terminals are unused and one or more RTB
RTN-x terminals are used, then one or more of the IF6CIS channels has an
external loop supply, and you must use the following format.
If Floating Point Configuration: Communication Format is Float Data or CST Time Stamped
Float Data
Set the ChxConfig.TenOhmOffset configuration tag to a non-zero value for
each channel that uses an external loop power source. This tag was previously
ignored by the 1756-IF6CIS module.
