3.6.4 Using Subscripts I and J
Two types of register, I and J, are used exclusively for modifying relay numbers and register
numbers. I and J have exactly the same function.
An example of each register data type is explained below.
„ Subscripts Attached to Bit Data
When subscript i or j is attached to bit data, the value of I or J is added to the relay number.
For example, if I = 2, MB000000i will be the same as MB000002. If J = 27, MB000000j will
be the same as MB00001B.
„ Subscripts Attached to Integer Data
When a subscript is attached to integer data, the value of I or J is added to the relay number.
For example, if I = 3, MW00010i will be the same as MW00013. If J = 30, MW00001j will
be the same as MW00031.
„ Subscripts Attached to Double-length Integer Data
When a subscript is attached to double-length integer data, the value of I or J is added to the
relay number. For example, if I = 1, ML00000i will be the same as ML00001. ML00000j
when J = 0, and ML00000j when J = 1 will be as follows:
„ Subscripts Attached to Real Number Data
When a subscript is attached to long integer data, the value of I or J is added to the relay num-
ber. For example, if I = 1, MF00000i will be the same as MF00001. MF00000j when J = 0,
and MF00000j when J = 1 will be as follows:
