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 CLV
firmware V 2.0. The connector cover covers the two connections of the CLV 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 of the CLV.
Notes
If the CLV 480 is used to replace a CLV 265/CLV 295 equipped with a connector cover (pa-
rameter memory), the CLV 480 cannot store its extensive parameter set in this external pa-
rameter memory (too small).
The external parameter memory is available in different implementations:
10.3.1
Function
When it is started, the CLV is initialized with the data stored in its internal parameter set. If
this parameter set has been copied to an external memory, the device can be replaced ea-
sily. 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 me-
mory was accessed successfully. The CLV also outputs messages for troubleshooting pur-
poses on the terminal interface.
