The figure below shows the side and front views of the C200HW-PRM21.
The front view shows the indicator LEDs, the 'Machine No.' rotary switch, two
9-pin female sub-D connectors, and the bus termination switch.
The C200HW-PRM21 has 6 indicator LEDs. The two LEDs on the left side
give a status indication of the unit in general. The four LEDs on the right side
are related to the status of the PROFIBUS-DP network Refer to section 5-4
for a detailed (functional) description of the LEDs.
The rotary switch is used to set the unit number (or so called "Machine No.").
The unit number setting determines which words in the Internal Relay and
Data Memory Areas are allocated to the Master Unit.
The allowed unit number setting range depends on the PLC CPU Unit being
used, as shown in the following table.
