2.3.20 Numbering of the digital inputs (CANopen bus).
NDIMOD
Total number of digital input logic blocks.
Possible values: From 0 to 42.
Default value: 0 (no numbering is defined).
Associated variable: (V.)MPG.NDIMOD
This parameter shows the number of logic blocks that the digital input modules connected
to the CANopen bus are divided into. After defining this parameter, it is possible to set the
numbering of the digital inputs of each logic block by assigning a base index to the first of
them.
• In RIO5 and RIOR nodes, each module is a logic block, several modules cannot be
grouped in a block or divide a module into blocks. The logic blocks must have the same
number and size as the modules physically detected in the bus.
• In the RIO5 nodes, each double module (module with two boards) it counts as two, in
other words, two logic blocks.
• In RIOW nodes and third-party nodes, it is possible to display as many logic blocks as
desired, both in number and in size.
If this parameter is not set, the CNC numbers the digital inputs sequentially according to the
order of the modules in the bus.
DIMODADDR
Base addresses of the digital input logic blocks.
This parameter shows the table to set the digital input logic blocks. The following fields must
be defined for each block.
The configuration must meet the following requirements. If the parameters are not set
according to these requirements, the CNC will ignore it and it will number the digital inputs
sequentially according to the order of the modules in the bus.
• The parameters of all I/O nodes of the bus must be set; no node can be left undefined.
• The parameters of all the resources of a node must be set; no I/O can be left without a
number.
• The maximum number of logic blocks in the system will be 64, both for digital inputs and
digital outputs.
• The number of I/Os in a logic block must be other than zero and a multiple of 8 (8, 16,
24, 32, ...1024).
• The values of the base index must be comply with the formula "8n + 1" (i.e. 1, 9, 17, 25,
etc.).
• The blocks may be distributed at will within the range of resources managed by PLC
(1...1024). The PLC admits blanks, but the blocks cannot overlap; in other words, a PLC
digital input or output can only belong to a single node-module of the bus.
NODE
Node number of the header to which the I/O logic block belongs.
Possible values: From 1 to 126.
Default value: 0.
Associated variable: (V.)MPG.DIMODNODE[nb]
Node number of the header to which the I/O logic block belongs. The parameters of all I/O
nodes of the bus must be set; no node can be left undefined.
Column. Meaning.
MNEMONIC Mnemonic of the logic block.
NODE Node number of the header to which the I/O logic block belongs.
BLOCK Number of the logic block.
ADDRESS Base address of the logic block.
NDI Number of digital inputs of the module.
