Programming Console Operations

3-3-1 Testing ID Communications

This operation can be used to show the status of errors generated by executing

either a read or a write communications operation repeatedly every second for a

specific Data Carrier address. In the read test, one byte is read from the Data

Carrier repeatedly, while in the write test one byte is written to the Data Carrier

repeatedly. This operation is possible in PROGRAM mode only.

Data contained in the Data Carrier will not be overwritten, so the test can be used

for checks and other operations at system startup. At the same time, this func

tion can also perform various adjustment tests, such as on-site adjustment of the

distance between the Data Carriers and the Read/Write Head.

1. Monitor the content of word SR 234 in the ID controller.

. Display bit SR 23209. and select the test mode (read or write) by turning

SR 23209 ON or OFF with the Set or Reset Key. (A read test is specified in

the following example.)

Read test: Turn OFF SR 23209.

Write test: Turn ON SR 23209

During the test, the T/R indicator for the ID function will flash, and the test

results will be placed in word SR 234. as shown below.

FFFF: ID communication in progress

0x00: Normal end

0xxx: Error end

4. Refer to ID Communications Errors on page 178 for the meaning of error

messages and error codes.

5. When the next communication is executed normally, the error display will

automatically leave the screen.

6. Turn off bit 23208 to cancel the test or before shifting to the another opera

tion. The following display shows a normal ending for the test

Reading the ID Error Log

When the ID Controller is running in the operating mode, information on various

types of errors is stored in the DM area in the ID Error Log and in the ID Error

Statistics Log. This information can be displayed on the Programming Console

as error messages.

ID Error Log

ID Error Statistics Log

The last 30 errors are displayed in order of the error log data number.

The numbers of ID communications errors generated are displayed by the type

of error.

Note The ID Error Log and ID Error Statistics Log may or may not be stored in memory

depending on ID Controller Setup. ID error log information is stored in one of two

ways, leaving either the newest error or the first 30 errors. Refer to 5-1 ID Con

troller Setup for details.
