Communicating with the FD-MH series

(5) The current values of the sensor amplifiers of the specified ID numbers are entered into current value

boxes 1 to 3.

If the current value is over range, under range, or invalid, the previous value is retained without

updating the current value. Use the value with the judgment value property.

(6) When the "request to change current value page" command is

set to 0, the "current value page

change complete" parameter flips to 0. If a current value page change error occurred, it is cleared

(0).

(7) Once the current values of the sensor amplifiers are updated, the current value boxes are updated by

cyclic transfer.

 Monitor mode 2/full mode

When reading current values in monitor mode 2 or full mode, read the remote

registers assigned to the ID numbers of the sensor amplifiers. For details of remote

registers, see "Device Maps" (page 3-4).

When reading current values in monitor mode 1, see "Monitor mode 1" (page 3-

18).

This example illustrates how to read the current values from the sensor amplifiers of ID 01, 02, and 03.

(1) When the current value of a sensor amplifier is updated, the new comparator value is entered into

remote register RWr.

If the current value is over range, under range, or invalid, the previous value is retained without

updating the current value. Use the value w

ith the judgment value "invalid", "over", or "under".

(2) If the current value of a sensor amplifier is "invalid" (----), the bit corresponding to the ID number of

that sensor amplifier flips to 1.

(3) If the current value of a sensor amplifier is "over" (FFFF), the bit corresponding to the ID number of

that sensor amplifier flips to 1.
