Page 2/2: Error Status (Ver. 1.4x or earlier)
• Error status elds contain the error type and the date it occurred (YYYY/MM/DD HH/MM/SS). (See the example below.)
• When more than one error among the errors 1 through 5 has occurred, the only most critical error is displayed. Priority is
given as in the table below.
ERROR No. MESSAGE PRIORITY REMARK
1 EEPROM database
HIGH
↕
LOW
2 PV
3 MV feedback
4 Function block
5 Control overload
6 Modbus communication ---- SC200/210 only
7 Backup module ---- SC110/210 only
For example, only the error 2 is displayed while both the error 2 and 3 are true. Then the error 3 is displayed after the error
2 is cancelled.
• One of the errors 1 through 5 plus the error 6 and/or 7 can be displayed at once.
• Refer also to Appx 5. DIGITAL DISPLAY ERROR MESSAGES.
Note
When a control overload error is occurring, the control cycle gets slow automatically. Error status is still displayed even if
the power supply is reset until ‘0’ is set in both Group 00 and Item 40.

Red bar blinks during error.
