Monitoring for Correct Operation of G9SP-series Controller
104
The G9SP-series Controller communicate with a Standard PLC through an
RS-232C Serial Communications Board (CP1W-CIF01) or an Ethernet Com-
munications Board (CP1W-CIF41).
This section provides examples of connections with an OMRON PLC. It gives
the communications specifications and provides examples of applications for
Option Board communications. Examples of connections to a PLC from
another manufacturer are described in the G9SP Host Connection Manual
(Cat. No. Z924).
This section describes the features of the G9SP-series Controller's Option
Board communications.
Select from two types of communications according to the application. The
use of no-protocol RS-232C serial communications and Ethernet UDP/IP
enables communications with both non-OMRON Standard PLCs and
OMRON PLCs. Communications with OMRON PLCs can be performed using
the FINS/UDP protocol.
Settings at the G9SP-series Controller are not required to use RS-232C serial
communications. Only TCP/IP settings are required to use Ethernet communi-
cations. In addition, connection at the Standard PLC can be easily made by
following the sample ladder programming and the setting examples in the fol-
lowing descriptions.
Monitoring can be performed for operation status with detailed information on
any errors that occur in the G9SP-series Controller. In particular, for Safety
I/O terminals, you can check the cause of an error, such as a short-circuit or
ground fault to 24 V, rather than simply the number of the terminal at which the
error occurred.
Data received by the G9SP-series Controller can be used in the program.
You can monitor whether the G9SP-series Controller is operating correctly by
using the G9SP-series Controller's Unit Normal Operating Flag and Present
Error Information. The Unit Normal Operating Flag turns ON when the Unit is
operating in RUN Mode and no errors have occurred. When this flag is OFF,
an error has probably occurred. Therefore, check the Present Error Informa-
tion to identify the error in the G9SP-series Controller.
Standard PLC
The information that is required to monitor the
G9SP-series Controller is sent as a package.
