Unit Components
Section 2-2
6.
Input Indicators
The input indicators are lit when the corresponding input terminal is ON.
The status of an input indicator will reflect the status of the input even when
that input is being used for a high-speed counter.
Note a)
When interrupt inputs are used in interrupt input mode, the indica-
tor may not light even when the interrupt condition is met if the in-
put is not ON long enough.
b)
Input indicators will reflect the status of the corresponding inputs
even when the PC is stopped, but the corresponding input bits will
not be refreshed.
7.
Output Indicators
The output indicators are lit when the corresponding output terminal is ON.
The indicators are lit during I/O refreshing. The status of an output indica-
tor will also reflect the status of the corresponding output when the output
is being used as a pulse output.
8.
Communications Port
Connects the PC to a Programming Device (including Programming Con-
soles), host computer, or standard external device. Use a proper Connect-
ing Cable (CPM2C-CN111, CS1W-CN114, or CS1W-CN118).
Note a)
A CQM1H-PRO01-E Programming Console can be connected di-
rectly to the PC.
b)
A C200H-PRO27-E Programming Console can be connected di-
rectly to the PC with a CS1W-CN224/CN624 Connecting Cable.
c)
Use a CPM2C-CN111 or CS1W-CN114 Connecting Cable to con-
nect to the communications port as a peripheral port. The commu-
nications port can be used simultaneously as both a peripheral
port and RS-232C port by using the CPM2C-CN111 Connecting
Cable.
d)
Use a CPM2C-CN111 or CS1W-CN118 Connecting Cable to con-
nect to the communications port as a RS-232C port. The commu-
nications port can be used simultaneously as both a peripheral
port and RS-232C port by using the CPM2C-CN111 Connecting
Cable
9.
DIP Switch
The DIP switch settings determine the DeviceNet communications speed
and control the communications settings for the communications port (pe-
ripheral port and RS-232C port).
• DeviceNet communications speed
