DATA CONVERSION

RESPONSE TIME
Response time of analog input module (R7G4HH-A-SVF4; slave) is time from when 0 to 100% stepwise signal change is applied to the module until the communication ASIC of the module transmits 90% of input signal.

TCOM: HLS scan time
HLS scan time varies according to communication method, the number of operating slave stations (FS), transmission rate (TBPS), and the hop count (LF).
· Full-duplex communication
LF = 0     : HLS scan time = 182 x FS x TBPS (sec.)
LF = 1 to 7: HLS scan time = (184 + (144 x LF)) x FS x TBPS (sec.)
· Half-duplex communication
LF = 0     : HLS scan time = 354 x FS x TBPS (sec.)
LF = 1 to 7: HLS scan time = (328 + (144 x LF)) x FS x TBPS (sec.)

TINP: Input unit response time ≤ Delay time of input circuit (Ta) + (Conversion rate x Moving average order) (Tb) + Input internal processing time (Tc)  (HLS scan time x 2)

e.g.
Number of moving average: 1,
Communication: Full-duplex,
Number of operating slave station (FS): 63,
Transmission rate (TBPS): 12Mbps,
the hop count (LF): 0
HLS scan time (TCOM): 182 x 63 x 1 / 12 M = 0.9555 [msec.]
Input unit response time (TINP): Delay time of input circuit (1 msec.) + Conversion rate (0.2 msec.) x Number of moving average (1 time) + Input internal processing time (0.9555 msec. x 2) = 3.1 [msec.]

I/O DATA DESCRIPTIONS
Scaling of analog input module is configurable with the configurator software (model: R7CFG). Refer to the software manual for details.
