5.7.3 Machine parameter settings
CAN-I/O parameters
I/O configuration of the CAN bus (P30)
In machine parameter P30, 2 input blocks and 1 output block are inten-
ded for the SR-CAN module.
A CAN block consists of up to 8 bytes data. An analog channel of the SR-
CAN module consists of 2 bytes data. For the 4 analog input channels,
one input block will be assigned.
The second input block is required for the digital inputs (1 byte data). The
output block is required for the digital ouptut (1 byte data).
CAUTION
In order to use the analog inputs of the SR-CAN module, the di-
gital outputs of the module must also be taken into account on
the rho4 side.
Is this not the case, the transmission of the inputs will also be
interrupted and the rho4 signals the status : “No transmission
CAN”.
In order to use the analog inputs of the SR-CAN module, it is not neces-
sary to set the subparameter ’Number of the SR-CAN module’. But if it is
set, the parameter P37 ’Electrical type plate’ must then be adapted.
(Siehe also section 5.6.)
After P30 has been entered, the address ranges of the I/O blocks are to
be adapted in P31 and P32.
Address range of the CAN-Inputs (P31)
The machine parameter P31 configures the CAN ínputs. For each input
block, the subparameters I/O type, initial address, block length, identifier
and CAN-Bus number are to be adjusted (see also Analog I/O with
CAN-B~IO modules, section 5.5.2).
Example
For the configuration of a SR-CAN module at the CAN bus 2 and adju-
sted node-ID=3, the following settings are to be entered under machine
parameter P31:
1. Analog-input block
