1-1 Features
• A maximum of four sensor modules in any combination and order can be
mounted to a single CQM1-SEN01.
• Sensor modules can be connected to the CQM1-SEN01 via connectors
and the CQM1-SEN01 can supply power to the modules, thus greatly sav-
ing wiring effort.
• The sensitivity of each sensor module is set by teaching. After power is
supplied to sensor modules mounted to the CQM1-SEN01 and teaching
is executed, the sensor modules will function properly. Teaching can be
executed remotely by using the dedicated CQM1-TU001 Remote Console
(sold separately).
• If the mode selector of each sensor module is set to SET, no signal is
transmitted to the PC. Signals are transmitted according to the sensor
operation only when the mode selector is set to RUN.
• At the time of system testing, no signals from Sensor Units will be
retrieved by the PC if the Programming Console connected to the PC is in
program mode.
1-2 System Configuration
The CQM1-SEN01 is a four-point input unit that occupies one input word. All
bits, other than input bits, will not be used as work bits.
It is recommended that the CQM1-SEN01 be mounted to the left of the
CQM1-OC@@@ Relay Contact Output Unit but not next to the CQM1-
OC@@@ Relay Contact Output Unit, otherwise the sensor modules mounted
to the CQM1-SEN01 will be influenced by noise that may be generated from
the CQM1-OC@@@ Relay Contact Output Unit at the time of load switching.
The following illustration shows a CQM1H/CQM1 system configuration that
includes the CQM1-SEN01.
