I am trying to access a hardware alarm for a CIOC in a Condition Block. The expression I am using is '//CIOC-1/MAINT_ALM.CV' != 0 . I have also tried   '//CIOC-1/MAINT_ALM.LAALM' != 0 . Using a PK controller.

When online with the module and I go inside the Condition block expression the the '//CIOC-1/MAINT_ALM.LAALM' shows a value of 8195, however the output of the condition block is 0. The condition block also shows a Readback Failed in the BLOCK_ERR field.

Looking for a way to use the hardware alarm fields in a condition block so I do not get the error.

Also of note; The ADVISE_ALM.CV , FAILED_ALM.CV and THE MAINT_ALM.CV all show a value when viewed in the condition block online, however; the COM_ALM.CV will not. The same for the .LAALM fields.

Thanks in advance for any help,
