Data upload time (internal memory address %UDa.b.10~13)

1. It is an area to store the updated interval. (Time: the count of data 1 in the
applicable area is 0.1ms.) When module data is updated the data is shared with
MasterLogic-200.
2. If temperature is controlled by MasterLogic-200 PLC, the data is used to decide the
controlling cycle. (See Programming for application example.)

Alarm (PVA/RCA) enable/disable (internal memory address %UXa.b.464~471)

1. Bit 468~471: The alarm(PVA/RCA) enable/disable alarm function is activated only
if the alarm output enabling bit of the specific channel is set to 1.
2. Bit 464~467: Maximum/minimum search enable/disable or change in value
displays the maximum/minimum detection enabling bit of the applicable channel set
to 1. Once the bit is set to 0, maximum/minimum value will not be detected. But the
last detected maximum/minimum value will be saved.
