5. Example of DN211 Applications
This chapter describes an example of operating the DN211 from the T2/T2E/T2N and a sample
ladder program.
CAUTION
1. This chapter describes an example of operating the DN211's functions from the T2/T2E/T2N
and a sample ladder program. It also explains subjects necessary to use the DN211. Thus,
try to understand the DN211 well before writing programs. Because the sample program is
basic, ample discussion is needed before applying to real systems.
2. When the T2/T2E/T2N changes to the HALT/ERROR mode from the RUN mode, the DN211
in run mode will change to standby mode.
5.1 The DN211 Operation Order
Figure 5.1 illustrates steps from switching ON the DN211 power, setting the module, writing output
data, and to reading input data.
Setting the operation mode:
Run mode
Reading input data
Writing output data
Checking slave devices
Setting the module
setting parameters of the local
station and slave devices
Switching On the power
Inputting/outputting
slave data
Synchronous mode
or
asynchronous mode
