BL20 - Communication in CANopen
D301087 0308 - BL20 CANopen4-232
Object 6B00
hex
– CAM State Register
Object 6B00
hex
(corresponds to object 6300
hex
in accordance with
CiA DS-406) indicates whether the current counter status is within a
specified range. This range is limited by CAM1 Low Limit (object
6B10
hex
) and CAM1 High Limit (object 6B20
hex
).
On the BL20 counter module the behaviour is only defined in accor-
dance with CiA DS-406 by means of the appropriate configuration
and operating mode selection:
Operating mode is set to Counting
The operating mode for DO1 is set to Switch on when counter
status ≤ reference value1.
The operating mode for DO2 is set to Switch on when counter
status ≥ reference value2.
The release bits for DO1 and DO2 are set.
The following should be observed:
The object 6B10
hex
"CAM1 Low Limit" corresponds to reference
value2 of the BL20 counter module.
The object 6B20
hex
"CAM1 High Limit" corresponds to reference
value1 of the BL20 counter module.
These two reference values 1 and 2 are assigned to outputs DO1
and DO2.
The object 6B00
hex
"CAM 1 State Register" supplies the result of
the AND operation of the two outputs DO1 and DO2.
Note
The object 6B00
hex
is only valid if the counter module is operating in
count mode.
