Judgment form
a) 5V DC control current capacity check
b) Input/output point connection upper limit check
If all the above conditions are met, the extension and special function blocks can be con-
nected to the base block.
If one of the above conditions is not met, reduce the number of input/output points or
number of blocks, or change the types of blocks to be connected.
