• The error history registers 15 errors at a maximum. If 16 or more errors occur, errors are deleted from the

• If the same error occurs continuously, only the error that occurred first is stored to the error history.
• Even after the power of the module is turned off and on, the error history remains.
• To initialize the error history, set "Method selection" to "Error history clear request" on the "Command
Execution of Slave Station" window and click the [Execute] button.
