BL20 - Communication in CANopen
D301087 0308 - BL20 CANopen4-162
The structure of the 2 bytes of parameter data depends on the
module concerned. A sub-index is assigned for each channel. The
following explains the structure for each module type:
BL20-1AO-I(0/4...20MA)/ BL20-2AO-I(0/4...20MA)
BL20-2AO-U(-10/0...+10VDC)
Table 101:
Parameters BL20-
xAO-I(0/4...20MA)
A default setting
Byte Bit Parameter Value/ Meaning
n 0 Current mode 0 = 0...20 mA
A
1 = 4...20 mA
1Value
representation
0 = Integer (15 bit + sign)
A
1 = reserved)
Only for BL20-2AO-I(0/4...20MA):
3 Channel Kx 0 = activate A
1 = deactivate
n +1
and
n + 2
Substitute Value A1 The substitute value will be
transmitted if the respective
parameters of the gateway
have been set to „output
substitute value“.
