3.2.1 Route Values
1 to 64
The Routing Path is required by the Modbus Plus module and the Modbus Plus
chipset to address specific nodes on the network. The routing path allows the
module to support the addressing of nodes separated by Bridge Multiplexers,
and to define Data Slave input paths for devices requiring path specifications
(that is, other ModConnect Program devices). Up to 64 devices may be defined
in this section.
Note the following when entering addresses:
Programmable Controllers: When addressing these devices, the last non-zero
byte in the routing specifies the network node address.
Example: 6 0 0 0 0
Addresses a PLC at Node Address 6.
ModConnect Type Devices: When addressing these devices, including other
MBP modules, the next-to-last non-zero value specifies the Slave Data Path to
use (1 to 64). An incorrect value in the Slave Data Path will cause
communications to fail.
Example: 6 1 0 0 0
Addresses Node Address 6 through Slave Data Path 1.
3.2.2 Global In Length
0 to 32
The Global Input Length defines how many words of Global Input Data the
module will be expecting from each of the network nodes. If less data is returned,
an error code is returned to the module status table and the data is rejected.
Conversely, if more data is returned, it is accepted and no error is flagged.
Valid values range from 0 to 32. Note that a value of 0 tells the MBP module not
to request Global Data from a node.
3.2.3 Global In Address
0 to 3999
The Global Input Address tells the module where to place the Global Input Data
received from the network nodes into the module’s database. Valid locations are
from 0 to 3999.
