There are two OEM parameters included in the first rack (DO Board). These OEM parameters define
the primary module position; declaring the module’s chassis and slot location. There is no need to
define the secondary module position within the
IEC1131 TOOLSET . Where systems may be required to
start-up with modules in the secondary position as the active module, e.g. primary module is not
installed when application is started, the secondary module’s position should be declared in the module
definition of the System Configuration Manager.

Table 4 OEM Parameters
All of the racks except for 5 (MXOUT), 9 (HKEEPING), and 10 (INFO) have 40 sequentially numbered
channels that start with 1. The first channel (1) and all subsequent odd channels pertain to the control
functions, while the second channel (2) and all subsequent even channels pertain to the test and
feedback functions. Channel 1 (for control) and channel 2 (for test/feedback) together represent the
complete interface to the field device 1. Subsequent consecutive pairs represent the interfaces for field
devices 2 through 20.
The TMR 24Vdc Valve Monitor module provides more information about the feedback input and valve
test status than is available on a per-rack basis. To accomplish this, a logical data mux is used to
select one of the possible return values. The MXOUT signal allows the user to request a specific data
item, the MXIN signal tells the user which data item is currently available, and the MXDAT value
contains the data item. There is a separate MXOUT, MXIN, and MXDAT for each field device.
A complete list of data items (i.e. valid MXOUT and MXIN values) is provided after the rack definitions.
