Using Programming
Software in Your FLEX Ex
Application When using FLEX Ex thermocouple/RTD/mV modules, you must
perform I/O mapping and configure the ControlNet network before
generating configuration data for your I/O modules.
For example, you may use RSNetWorx™ to connect FLEX Ex I/O
modules to a ControlNet processor or scanner through a FLEX Ex
ControlNet Ex adapter (cat. no. 1797-ACNR15). The I/O configuration
portion of another programming software, for example RSLogix5™
could be used to generate the configuration data for each I/O module
in the control system.
Configuration data is then transferred to the controller during the
program download and subsequently transferred to the appropriate I/
O modules.
Follow these general guidelines when configuring I/O modules:
1. Perform I/O mapping.
2. Instruct the FLEX Ex I/O modules to use I/O mapping file from
step 1.
3. Configure all I/O modules.
About the ControlNet Ex
Adapter The FLEX Ex ControlNet Ex adapter (cat. no. 1797-ACNR15) interfaces
up to 8 FLEX Ex modules to a ControlNet processor or scanner. The
adapter can support ControlNet real-time data connections to
individual modules or module groups. Each connection is
independent of the others and can be from different processors or
scanners.
Communication Over the
FLEX Ex Backplane One 1797-ACNR15 ControlNet Ex adapter can interface up to eight
terminal base units with installed FLEX Ex modules, forming a FLEX
Ex system of up to eight slots. The adapter communicates to other
network system components (typically one or more controllers or
scanners, and/or programming terminals) over the ControlNet
network. The adapter communicates with its I/O modules over the
FLEX Ex backplane.
