● When a value out of the setting range above or a value which does not satisfy the formula of process alarm upper upper
limit value ≥ process alarm upper lower limit value ≥ process alarm lower upper limit value ≥ process alarm lower lower
limit value is set to a channel, an error occurs in the channel. The error code is stored in Latest error code (Un\G19), and
Error occurrence flag (XF) is turned to ON. The operation is performed in the setting configured before the error
occurrence.
