with different priority levels.

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.
J
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.

J
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.
