BL20 - Communication in CANopen
D301087 0308 - BL20 CANopen4-124
Object 6220
hex
- Write Output Bit (1 to 128)
Object 6221
hex
- Write Output Bit (129 to 256)
Object 6222
hex
- Write Output Bit (257 to 288)
The objects are a bit-wise representation of the values of the digital
output modules. Each sub-index for these objects is a Boolean
value.
A total of 128 bits can be represented (128 digital output channels).
If more than 128 output channels are present, then object 6221
hex
is
used.
If more than 256 output channels are present, then object 6222
hex
is
used.
Since the number of digital input channels in a station is limited to
288, it is not possible to make use of the complete range of the array
in object 6222
hex
.
