Alarm Mode 5: Tested Not-Clean
Output 1
Output 2
Turns on When
Test Complete
>Lower
Intended Function
Test Complete Signal
“Not Clean” Signal
This is used when controlling tests from a PLC using switched outputs. The PLC gives a start signal, then monitors
the "Test Complete’’ output. If the test has failed
it can detect this with the "not clean’’ signal.
``Continuous testing’’ should not be selected for this mode.
Alarm Mode 6: Testing Not-Clean
Output 1
Output 2
Turns on When
Testing
>Lower
Intended Function
Test in progress Signal
“Not Clean” Signal
This is similar to mode 5 above. The difference is that output 1 is active during the test and turns off at test end.
``Continuous testing’’ should not be selected for this mode.
Alarm Mode
7… Customer Requested Modes
Other alarm modes will be defined as and when customers request them.
6.4 Standard Communication Protocols
6.4.1 Modbus
The CMS can be controlled via commands on its serial (RS485) interface, using the Modbus RTU protocol. It is
possible to control every aspect and setting of the CMS, as is done by the RMF-View control software. All results
and counts are available in all supported formats. We suggest using RMF-View to initially configure the CMS and
check it is performing correctly, and then the customer-written software only has to read the test results. This
could be used to integrate the CMS measurements with a general machine control, vehicle control or factory
monitoring system.
Customers wishing to implement their own Modbus controller software will need to refer to the rest of this
section with further details in section 11.1 and 11.2.
The simplest arrangement is to configure the CMS to test continuously, with a set interval between tests.
For example; a Test Duration of 2 minutes and a Test Interval of 10 minutes.
The Start Testing Automatically selection can be used so that the unit does not require a start signal.
Then, the most recent test results can be read from the appropriate Modbus Registers.
