Installing and operating the external parameter memory
The external parameter memory is available as an accessory. It is located in a connector
cover and comprises a permanent, rewriteable memory (EEPROM) with 4 kByte from CLX
firmware V 2.0. The connector cover covers the two connections of the CLX in the enclosure
rating IP 65. The cover is shown in
.
Two connection cables that are secured by
means of conduit thread connections supply the signals to the CLX.
The external parameter memory is available in different implementations:
10.3.1
Function
When it is started, the CLX is initialized with he data stored in its internal parameter set. If
this parameter set has been copied to an external memory, the device can be replaced
easily. The replacement device, therefore, does not have to be configured manually. Instead,
it accesses the external parameter memory automatically (assuming that the correct start
option has been selected). It then imports the parameter set to its RAM. This option is set
by default. The "Device Ready" and "Read Result" LEDs indicate whether the external
memory was accessed successfully. The CLX also outputs plain-text messages for trouble-
shooting purposes on the auxiliary interface.
