CONFIGURATION
Configuration I/O Screen
The next available configuration option is “
I/O”
which produces the following display:
There are three “
I/O”
options available.
1.
Comm. Setup
- This allows the
operator to specify RS-232/422
options.
STD. Comm.
option activates a
continuous 232 output stream which
includes the product number, the
process measurement, and
temperature. The format is as
follows:
[01 35.13, 43.6]
For this example, 01 is the product
number, 35.13 is the process
measurement, and 43.6 is the
temperature.
PC Comm.
option allows communication with a remote PC. This option requires a remote PC
with EMC software installed to establish communications. The PC software is a statistical
analysis package that can be used to monitor up to 4 on-line MPR E-Scan units.
2.
Baud Rate
- Is the selectable transmission rate for the communications.
The 232/422 is preset to a default setting displayed. However, the baud rate is user selectable
and is used for all communications configured in the “
Comm. Setup”
option.
3.
Unit Num
- This is used to identify the instrument by a number when configured for PC
communications. This option is used to identify the MPR E-Scan when configured for PC
communication. Each MPR connected to the remote PC would have a designated unit number.
The PC software will communicate with up to four on-line MPR E-Scan units.
In cases where a remote protocol interface is used in place of the PC communications software
from EMC, each MPR being addressed can have a designated unit number in the range of 1-255.
In addition the decimal base 10 unit number is converted to support ASCII hex protocol to
comply with standard fieldbus applications. The ASCII hex equivalent is displayed in
parenthesis above. (See RS-232/422 Protocol addendum.)
