CAN-Bus peripheral equipment
D
Block length:
The block length has for all analog modules that are available at the
moment 8 bytes (4 channels).
D
Identifier:
A bus switching can supply a maximum of input blocks (32-I-byte) and
4 output blocks (32-O-Byte).
The CAN identifier for the corresponding input block results from the
node-ID set by means of the hardware of the B~IO M-CAN-modules:
Input Block Input Byte CAN-Identifier
1 1 to 8 384 + Node-ID
2 9 to 16 640 + Node-ID
3 17 to 24 384 + Node-ID + 1
4 25 to 32 640 + Node-ID + 1
D
CAN-Bus-Number:
The CAN-Bus number indicates with which of the both CAN busses fo
the rho4 the B~IO modules are operated. Only the numbers 1 and 2
are authorized. They correspond to the CAN plug number X51 and
X52.
Examples: CAN input parameter
Example1:
A bus switching B~IO M-CAN is operated together with an analog input
modules 4AI_UI. The node-ID of the B~IO M-CAN modules is set via the
DIP switch on the value 7. The module is connected via the CAN plug
X52 to the rho4.
As CAN identifier to be set, it follows:
384 + 7= 391
