Usage Method for Suffixes I and J
Two types of dedicated register, I and J, have been provided for modification
of relay numbers and register numbers. The functions of I and J are exactly
the same. Examples of each register data type follow below.
If the suffix is in bit form
The value of I is the same as the value of J when added to a relay number.
For example, when I = 2 MB000000l is the same as MB000002. When J = 27
MB000000J is the same as MB00001B.
If the suffix is in integer form
The value of I is the same as the value of J when added to a register number.
For example, when I = 3 MW000010l is the same as MW00013. When J = 30
MW00001J is the same as MW00031.

functions from drawings of different priority levels. By function
