9. Project File

This section describes the details on the project file used in this document.

9.1. Overview

This section explains the specifications and functions of the project file used to connect the Safety Controller (hereinafter referred to as the destination device or G9SP) to the Controller (Serial Communications Unit) (hereinafter referred to as an SCU Unit).

The project file means a Sysmac Studio project file. The following data has already been set in this project file.

·SCU Unit communications settings and program task settings

·Ladder program for serial communications

·Variable tables and data type definitions of the variables used in ladder programs

This project file uses the serial communications of the SCU Unit to execute “read the I/O monitor results” on the destination device and to detect whether the operation ends normally or abnormally. A normal end of this project file means a normal end of that the serial communications. An error end means an error end of the serial communications and a destination device error (Detected with the response data from the destination device).

Additional Information

OMRON has confirmed that normal communications can be performed using this project file under the OMRON evaluation conditions including the test system configuration, version of each product, and product Lot, No. of each device which was used for evaluation. OMRON does not guarantee the normal operation under the disturbance such as electrical noise or the performance variation of the device.

Additional Information

With Sysmac Studio, the “data type + #” prefix is added to decimal data and “data type + # + 16 + #" prefix is added to hexadecimal data when it is necessary to distinguish between decimal and hexadecimal data. (e.g., INT#1000 decimal -> INT#16#03E8 hexadecimal. For DINT, a data type + "#" are unnecessary.)

Serial cable

(1) (2) (3)

(1) Errors during execution of SerialSend/SerialRcv instructions (communications instruction

errors) An error end of SerialSend/SerialRcv instruction due to an incorrect SCU Unit setting or incorrect variable setting, etc is detected as a communications instruction error. The error is detected with the error flag (Error) at the execution of an instruction.

(2) SCU Unit errors (Unit errors)

An error that prevents the SCU Unit from being ready for communications is detected as a Unit error. This error is detected when a timeout occurs.

(3) Errors in the destination device (Destination device errors)

An error that occurs during communications with a destination device is detected as a destination device error. Destination device errors include a transmission error caused by a destination device's command error, parameter error, data error and an error that preven ts execution, character corruption or unmatched baud rate setting. The error is detected with the response data which is sent from the destination device. With this project file, the destination device error is detected when there is a difference between a normal receive message (hereinafter referred to as a normal message) and an error receive message (hereinafter referred to as an error message). (Refer to 9.2.3. Send/Receive Message for details.)
