6.3.3 Communication errors
(1) Network errors
When an error was found on the network of the IR.LINK module, the status error flag of the
NET status and the ALM of the S-register is turned ON and write error code (see table
below) into S-table.
In the S10mini, the following “error code” is displayed on the indicator of the CPU module.
In the S10V, an error code (ex. 0x7110) with “0x” appended to the beginning of the
following error code is displayed by selecting the error log from the S10V BASE SYSTEM.

Error code Explanation User response
7110 An undefined service was instructed. • If this error recurs even after the CPU (or LPU) has been
reset once and then set to the original position again,
restart the IR.LINK module.
• If this error still recurs, replace the IR.LINK module.
7120 The data length is incorrect.
7130 The packet configuration is incorrect.
2010 An error was detected during CRC check. • Check whether the network line is normal.
• Check whether SVPT setting matches station setting.
• If this error still recurs, replace the IR.LINK module.
2020 The station number is from 128 to 254 or
the received station number is incorrect.
2030 An undefined service was specified.
2040 The I-frame length is greater than or equal
to 137 bytes or the UI-frame length is
greater than or equal to 134 bytes.
2041 No I-frame exists in the I-response.
2042 An I-frame exists in the monitoring frame.
2050 Data link procedure error
2060 A timeout was detected (no response was
made from the slave station within the
specified time). • Power on the station again.
• Check whether the switches of the IR.LINK module and
station are set correctly.
• If this error still recurs even after the switches have been
set correctly, replace the station.
2061 The error could not be recovered by retry.
2070 No frame could be transmitted to the line or
an error was detected during frame
reception. • Check the network line connection and terminating
resistor connection.
• Check whether SVPT setting matches station setting.
• If this error recurs even after the CPU (or LPU) has been
reset once and then set to the original position again,
restart the IR.LINK module.
• If this error still recurs, replace the IR.LINK module.
2080 Other errors • If this error recurs even after the CPU (or LPU) has been
reset once and then set to the original position again,
restart the IR.LINK module.
• If this error still recurs, replace the IR.LINK module.
