7. You are now ready to view or change any of the parameters in the T2 CPU, and to view
the internal dynamic data in the Maxiflex System.
4.2 Configuring the Programming Port
This port is dedicated to the Programming and Configuration of the T2 CPU and CONET
systems, and requires no configuration to communicate with the CPU to which it is attached
(or its I/O modules). This port is permanently configured for the Conet/s protocol (operating
at 19,200 baud, 8 data bits, no parity, 1 stop bit.)
The only parameter configurable in the CPU for the Programming Port is its Global
Address.
It is possible to interrogate and program other remote network nodes in the system from this
programming port via any network port in the Maxiflex Base. The Network Routing Table
needs to be properly configured to use this function. See Section 4.7
When addressing remote nodes, the Programming Port’s Global Address is used to ensure
that the reply is returned to the programming port. Being used.
The CPU is shipped with the Programming Port Global Address set to 254. (See the “Setup
Programmers Global Address” Group in OMNISET/DITview.)
This global address must be reassigned if remote programming in the system is to be done
from more than one location at the same time.
If more than one CPU is connected in a network, they would all have the default global
address 254 (unless changed by the user on installation.) In this case, the reply from a
programming transaction would be returned to ALL programming ports set to this Global
Address. This is no problem if programming is only ever done at one CPU at a time.
In order to allow programming to be conducted simultaneously at more than one CPU in a
system at a time, each Programming Port should be assigned a unique Global Address. Set
a unique Global Address of each CPU Programming Port to be used simultaneously in the
system starting at 254 in descending order (254, 253, 252 etc,) These Global Address’s
assigned to the programming ports are then not available for use by other nodes in the
system.
4.3 Addressing a Module through the Programming Port
The first step when starting to configure a module in a Maxiflex System with a T2 CPU is to
select the address of the module. In Omniset, select the module to be addressed as follows:
From the pull-down menu select “Remote”, then “Target Address…”. (Depending upon the
dvx file being used, this menu item may say “File Target Address…” or “Group Target
Address”. These variations are explained in the Omniset Help file, and are not relevant to
the selection of the Target Address as discussed here.)
