3-3 Explicit Messaging

Communicating with the FD-MH series

- DeviceNet Compatible Network Unit DL-DN1 User’s Manual (FD-MH) -

*1 The error content of the sensor amplifier can be checked by noting the ON/OFF

state of each bit.

OFF (0): No error; ON (1): Error

More than one error may occur simultaneously. For details of each error, refer to

the FD-M Series Instru ction Manual.

*2 Details of output status can be checked by noting the ON/OFF state of each bit.

*3 If the instantaneous flow rate is above the upper limit of display rang

e ("FFFF" is

display

ed), the data will be NaN (exceeding the upper limit of display range). If

the sensor amplifier displays "ErH" the data will be "0".

The data is for "rESo" regardless of the display mode set on the sensor ampli-

fier.

*4 Data is read in minimum display units regardless of the integration display unit

set on the sen

sor a mplifier. If the integrated flow quantity exceeds the upper

limit, the da ta holds the upper limit value.

*5 The data will be "0" if no temperature sensor is connected. The data will be NaN

(exceeding the upper limit of display range) if the temperature is above the

upper display limit ("FFFF" is displayed).

*6 The saved da ta will be the one just before "ErH" if the sensor amplifier displays

"ErH".

*7 The data is similar to the settable range for "rESo" regardless of the display

mode set on the sensor amplifier.

*8 If a value 100.0 is written, a warning is not issued even when the temperature

exceeds the upper limit of tempera ture display range, but it is issued only when

the temperature falls below the lower limit setting.

*9 If a valu e 000.0 is written

, a warning is not issued even when the temperature

falls below the lower limit of temperature display range, but it is issued only

when the temperature exceeds the upper limit setting.

*10 If "analog output selection" is set to "standard", rewriting "free range analog

upper limit" or "free range analog lower limit" fails.

*11 Available only for FD-M (version A).

*12 An ASCII character string is sent back in response data (4 bytes). The data

types is DINT.

For "FD-M", the response is "46442D4Dh".
