44 Function Description WAGO-I/O-SYSTEM 750750-644 Bluetooth® RF-TransceiverManualVersion 2.0.0, valid from FW/HW Version 03/035.5 TimingIn “Real-Time Communication” mode, the 750-644 I/O module achieves lowtransmission and cycle times. The timing of data transmission is continuouslymonitored. If no data is received by the opposite side for a longer period of time, awarning and then error is indicated.The timing during normal operation primarily depends on the role in the piconetand the number of slaves connected to the master. For this reason, the time limits,which when exceeded indicate a warning or error, depend on these factors.Table 23: Timing of the 750-644 I/O module – time limitsName ValueBTCOM_WARNTIMEMaster, 1 slave linked:Master, 2 … 5 slaves linked:Master, 6 slaves linked:Master, 7 slaves linked:Slave:40 ms+20 ms per slave240 ms280 ms280 msBTCOM_ERRORTIMEMaster, 1 slave linked:Master, 2 … 5 slaves linked:Master, 6 slaves linked:Master, 7 slaves linked:Slave:80 ms+40 ms per slave480 ms560 ms560 msFor optimal timing, there must be a valid piconet configuration. If the master isunable to establish a link to all slaves, the attempts at reintegration of these slaveslead to interruptions in data traffic (see section “Function Description” > … >“Operation as a Slave in 'Real-Time Communication' Mode”).During normal operation, the timing falls well below the time limits specified inthe table “Timing of the 750-644 I/O module – time limits”.Pos : 69 /D okumentation allgemei n/Glieder ungs elemente/---Seitenwechs el--- @ 3\mod_1221108045078_0.doc x @ 21810 @ @ 1
