For bit or bit-and-word modules (but not for word-only
modules), the number for the I/O address must begin on an 8-
point boundary. An 8-point boundary is
(n
*
8) + 1
, e.g., 1, 9, 17,
etc. Addresses not starting on an 8-point boundary are changed
to do so when you write the values.
•
SoftShop does not flag duplicate I/O points. However, the Find
I/O functions under the PLC Configuration dialog box can be
used to search for duplicate I/O points.
To Edit the I/O Address:
1.
Select the slave module number address to be edited by double-
clicking on the module number, or by highlighting the module
number and then clicking on the Edit I/O Addr. button.
2.
Enter an I/O address that is a multiple of (
n
*8) + 1.
3.
After entering the I/O address click on the Accept button, then
the Close.
4.
Click on the Write All button to send the configuration for all
the slaves to the online controller or the offline program. Or
click the Write Slave(s) button to send the selected slave number
configuration to the online controller or the offline program.
NOTE
The standard for PROFIBUS-DP I/O (DIN 19245, Part 3)
stipulates certain bus parameters that cannot be changed while
communications are in OPERATE mode. If you modified those bus
parameters when you set up your configuration file in COM PROFIBUS,
set communications to STOP mode before you execute Write All or
Write Slave(s), in order to prevent bus errors.
