Input and Output Signal Timing when Connected to RCON-EC
When this product is to be connected to the EC connection unit (RCON-EC) and operation is to be conducted with a sequence program of PLC, the maximum response time since the control signal turns on until it reaches ELECYLINDER and then the ELECYLINDER status signal returns to PLC can be expressed in the formula below.
PLC → Maximum Response Time from PLC to ELECYLINDER : Yt + (Tt × 4) + Ft
ELECYLINDER → Maximum Response Time from PLC to PLC : Gt + (Tt × 2) + Xt
ELECYLINDER → Maximum Response Time from PLC to PLC : Gt + (Tt × 2) + Xt
Tt = Transmission time (5ms for RCON-GW or REC-GW and 2ms for RSEL)
Yt = Master station→Remote I/O station transmission lag time
Xt = Remote I/O station→Master station transmission lag time
Yt + Xt = Field network transmission lag time*1
Ft = Input Filter of ELECYLINDER*2
Gt = Input Filter of RCON-EC*2
Yt = Master station→Remote I/O station transmission lag time
Xt = Remote I/O station→Master station transmission lag time
Yt + Xt = Field network transmission lag time*1
Ft = Input Filter of ELECYLINDER*2
Gt = Input Filter of RCON-EC*2
*1 Refer to instruction manual for each field network master unit and mounted PLC for the field network transition latency.
*2 Ft and Gt differ depending on how to connect between ELECYLINDER and RCON-EC.
