Transition from Legacy
NCS Devices
The EIM (Ethernet Interface Module) and MIM
(MODBUS Interface Module) are now obsolete but
can be replaced with the EMM or any newer Interface
Module. There are a few minor differences to note.
Transition from EIM:
1. Re-Mapping of Status Bits.
2. I/O Module Registration.
Transition from MIM:
1. Re-Mapping of Status Bits.
2. I/O Module Registration.
3. Ethernet Connection required for configuration.
Re-mapping of Status Bits
The status bits have been reorganized into a single
system level register and various substatus registers.
Previously, all bits were located in a single register.
Now, if a bit is set in the system status register, you
are directed to a sub-status register for more detailed
information.
Systems which do not make use of these registers (i.e.
those in which the DCS/MODBUS Master does not
poll them) will not be impacted. If they are used, the
MODBUS registers/coils which are polled will need to
be updated. Refer to Appendix B for more information.
I/O Module Registration
The Interface Modules are now aware of the
I/O modules which are expected to be present. When
the attached I/O is changed, the user must use
the System Status Web page to click the “Accept
Module Types” button. Clicking on this button tells the
interface module that the currently attached module
types are correct. If the system is rebooted, and a
different module type or module count is detected, a
bit will be set in the Configuration Status Register.
Ethernet Connection for
Configuration
Configuration takes place via a network connection
(Ethernet). Please refer to NCS Configuration section
for more details.
