The number of communication words when conducting polling I/O communication can also
be set via Explicit message communication, or by the configuration tool or rotary switch.
However, when the number of communication words is set via Explicit message
communication, or by the configuration tool or rotary switch, the value set by the DIP switch
may be ignored.
5.4 Communication Environment Setting by Rotary Switch
Set communication environment of polling I/O communication of DeviceNet by using the “Node
address setting switch” and the “DeviceNet communication speed setting switch” which are the rotary
switch of the COM-JH.
The setting details cannot be check afterwards. When checking the details thus set, check
them via Explicit message communication. In addition, as each switch position is moved
during the setting, record the switch setting state before making the setting.
Setting procedure
1.
Turn off the power supply.
2.
Before communication environment, record the switch positions of node address setting switch
and DeviceNet communication speed setting switch. (When this module is used for the first time,
no recording is required.)
3.
Set all the values of a node address setting switch
and a DeviceNet communication speed setting
switch to “9.”
4.
Turning on the power sets the module to the
communication environment setting mode. If set
to the communication environment setting mode,
the RUN lamp goes off and the FAIL lamp
flashes.
5.
Select a setting item number with MSD of the node address setting switch, and set data with LSD
of the node address setting switch.
See
List of communication environment setting items (P. 24)
.
6.
Set the DeviceNet communication speed setting switch in the order of “9,” “0” and “1.”
The RUN lamp turns on and then it turns off after registration of the set data is complete (after a
lapse about 3 seconds).
7.
Repeat the steps from
5.
to
6.
of above, and set other setting items.
However, set the DeviceNet communication speed setting switch in the order of “1,” “0” and “1”
from the second setting.
8.
First check that the RUN lamp goes off, and then turn off the power.
9.
Return the switch positions of node address setting switch and DeviceNet communication speed
setting switch to the positions already recorded.
10.
Turn on the power again.
The set data valid if the power is turned on again.
