3 Expansion units
You connect the expansion devices directly to the PLC via the
easyLink interface. The following expansion devices can be used to
increase the number of PLC inputs and outputs.
Type overview of expansion devices
The EASY200-EASY coupling device enables you to connect a
remote expansion device to the controller via a 30 m 2-wire or
multi-core cable.
Overview of inputs/outputs
Inputs
Table 6: Number of inputs and symbolic operands
They are selected in the user program by means of the appropriate
syntax used in the PLC configurator.
Diagnostics inputs
The inputs R15, R16 provide you with additional information:
Table 7: Functions of the diagnostics inputs
The inputs can be scanned in the program with symbolic operands.
Outputs
Table 8: Number of outputs and symbolic operands
The transistor outputs are provided with a short-circuit monitoring
function. In the event that a short-circuit occurs at one of the
outputs, this is indicated via the diagnostics inputs R15/R16.
R15 is set to 1 if a short-circuit occurs at the outputs S1 to S4.
Input R16 is toggled if a short-circuit occurs on S5 to S6.
