The maximum program capacities of the CS/CJ-series CPU Units for all user
programs (i.e., the total capacity of all tasks) are given in the following table.
All capacities are given as the maximum number of steps. The capacities
must not be exceeded, and writing the program will be disabled if an attempt
is made to exceed the capacity.
Each instruction is from 1 to 7 steps long. Refer to 10-5 Instruction Execution
Times and Number of Steps in the Operation Manual for the specific number
