Cmpr3 Parm
Enter a Monitor Parameter in Compare 3 Parameter (CP-382) that will act on the value in Cmpr3 Val (CP-394), by using the
comparison type that you entered in Cmp3 Type (CP-388). If the comparison that is established by these three
parameters is “true”, then the PLC sets the Cmpr3 Out bit (62) in the PLC to “1” , which can be used to trigger a user
defined indicator.
NOTE: See Appendices: Appendix C for the Monitor Parameters that are not available for the Compare 3
Parameter (CP-382).
Cmpr3 Type
Use Cmpr3 Type (CP-386) to establish the type of comparison (see list below) that will compare the Monitor Parameter
that you entered in Cmpr3 Parm (CP-382) to the value that you entered in Cmpr3 Val (CP-390). If you require a
comparison that is not listed, then set the Cmpr3 Out bit in the PLC to “Ld Not”. This programs the comparison type
to become a “Not” statement For example, to program “Magnitude Less Than” (<) use “NOT” Magnitude greater than
or equal to(>=).
6 = ‘mag =’ if Magnitude of parm selected by Cmpr3 Parm) = Cmpr3 Val, Cmpr3 Out = 1
5 = ‘mag >=’ if Magnitude of parm selected by Cmpr3 Parm) >= Cmpr3 Val, Cmpr3 Out = 1
4 = ‘mag >’ if Magnitude of parm selected by Cmpr3 Parm) > Cmpr3 Val, Cmpr3 Out = 1
3 = ‘=’ if value of parm selected by Cmpr3 Parm) = Cmpr3 Val, Cmpr3 Out = 1
2 = ‘>=’ if value of parm selected by Cmpr3 Parm) >= Cmpr3 Val, Cmpr3 Out = 1
1 = ‘>’ if value of parm selected by Cmpr3 Parm) > Cmpr3 Val, Cmpr3 Out = 1
Cmpr3 Val
Enter a value in Cmpr3 Val (CP-390) that will be compared to the Monitor Parameter in Cmpr3 Parm (CP-382), using the
comparison type that you entered in Cmpr3 Type (CP-386). If the comparison that is established by these three
parameters is “true”, then the PLC sets the Cmpr3 Out bit (62) in the PLC to “1”.
Cmpr4 Parm
Enter a Monitor Parameter in Compare 4 Parameter (CP-383) that will act on the value in Cmpr4 Val (CP-395), by using the
comparison type that you entered in Cmpr4 Type (CP-389). If the comparison that is established by these three
parameters is “true”, then the PLC sets the Cmpr4 Out bit (63) in the PLC Programming screen to “1”, which can be used
to trigger a user defined indicator.
NOTE: See Appendices: Appendix C for the Monitor Parameters that are not available for the Compare 4
Parameter (CP-383).
Cmpr4 Type
Use Cmpr4 Type (CP-387) to establish the type of comparison (see list below) that will compare the Monitor Parameter
that you entered in Cmpr4 Parm (CP-383) to the value that you entered in Cmpr4 Val (CP-391). If you require a compari-
son that is not listed, then set the Cmpr4 Out bit in the PLC to “Ld Not”. This programs the comparison type to become
a “Not” statement For example, to program “Magnitude Less Then ” (<) use “NOT ” Magnitude greater than or equal
to (>=).
6 = ‘mag =’ if Magnitude of parm selected by Cmpr4 Parm) = Cmpr4 Val, Cmpr4 Out = 1
5 = ‘mag >=’ if Magnitude of parm selected by Cmpr4 Parm) >= Cmpr4 Val, Cmpr4 Out = 1
4 = ‘mag >’ if Magnitude of parm selected by Cmpr4 Parm) > Cmpr4 Val, Cmpr4 Out = 1
3 = ‘=’ if value of parm selected by Cmpr4 Parm) = Cmpr4 Val, Cmpr4 Out = 1
2 = ‘>=’ if value of parm selected by Cmpr4 Parm) >= Cmpr4 Val, Cmpr4 Out = 1
1 = ‘>’ if value of parm selected by Cmpr4 Parm) > Cmpr4 Val, Cmpr4 Out = 1
Cmpr4 Val
Enter a value in Cmpr4 Val (CP-391) that will be compared to the Monitor Parameter in Cmpr4 Parm (CP-383), using the
boundary type that you entered in Cmpr4 Type (CP-387). If the comparison that is established by these three
parameters is “true”, then the PLC sets the Cmpr4 Out bit (63) in the PLC to “1” .
