9．Program

Additional Information

9. Program

This section describes the details on the program in the project file that is used in this guide.

Overview 9.1.

The following explains the specificat i ons and functions of the program that are used to check the connection between the Digital Temperature Controller (hereinafter referred to as the "Destination Device") and the Controller (Serial Communications Unit (hereinafter referred t o as the "SCU")).

This program performs communications via CompoWay/F using the Serial Gateway function of the SCU, to send/receive the "Read Controller Attributes" command to/from the Destination Device and detect a normal end or an error end. A normal end of the send/receive processing means a normal end of communications via CompoWay/F. An error end means an error end of communications via Com poWay/F and an error of the Destination Device (identified in the response data from the Destination Device).

Here, the prefix "10#" (possible to omit) is added to decimal data and the prefix "16#" is added to hexadecimal data when it is necessary to distinguis h between decimal and hexadecimal data. (e.g., "1000" or "10#1000" for decimal dat a and "16#03E8" for hexadecimal data) The prefix "<data type>#" is also added to deci m al or hexadecimal data when specifying a specific data type. (e.g.,"WORD#16#03E8")

OMRON has confirmed that normal communic ations can be performed using this program under the conditions of 5.2. Device Configuration. However, we do not guarantee the normal operation under disturbances such as electri cal noise or device performance variation.

Error Detection Processing 9.3.

With this program, the error detection processing is performed according to the following descriptions (1) and (2). For information on error codes, refer to 9.7. Error Processing.

(1)Errors at the execution of the SendCmd ins truction (SendCmd instruction errors)

Errors such as a Unit error, a command format error and a parameter error are detected as SendCmd instruction errors when executing the SendCmd instruction. If an error occurs, the error code ErrorID or ErrorIDEx of the SendCmd instruction will be generated to identify the error. If an error in communications with the Destination Device is caused by a transmission error due to, for example, a character corruption or unmatched baud rate setting, the transmission error status (J01_P1_TransErrSta) that is the allocated variable area of the SCU will be stored in the output variable to show the communication error status.

(2)Errors in the Destination Device (Destinat i on Device errors)

Destination Device errors include a command err or, a parameter error and an execution failure in the Destination Device. An error is identified in the response data (receive data) that is returned from the Destination Device. If an error occurs in the Destination Device, the corresponding error code will be st ored in the end code or response of the receive data.
