PURPOSE:To always execute a normal control by setting an operating state a regulator to an auto mode, and using a set value used in the previous processing, in case when a setting circuit is normal and a set value read command does not exist, and in case when the setting circuit is abnormal. CONSTITUTION:When a setting circuit is abnormal, a regulator is set to an auto mode, a set value A12 used in the previous processing, which has been stored in the inside is inputted to a temporary storage memory P2, a processing of time lag of first order is executed to the contents of the temporary storage memory P2, and an output tracking processing is executed. On the other hand, when the setting circuit is normal, whether a set value read command exists or not is checked, and when the read command exists, a transmitted set value X2 is inputted to the temporary storage memory P2, and the regulator is set to a cascade mode. Also, when the read command does not exist, and when the regulator is not in the cascade mode, it enters the cascade mode. |
