Plc Link Response Time - Panasonic FP0R User Manual

6.7.6 PLC link response time

Ts (transmission time per station) = scan time + Tpc
Q
Tlt (link table sending time) = Ttx  Ltm
W
Tso (master station scan time)
E
Tlk (link addition processing time) = Tlc + Twt + Tls+ Tso
R
FP0R User's Manual
The maximum value for the transmission time (T) of one cycle can be cal-
culated using the following formula.
Tpc = Ttx  Pcm
Ttx = 1/transmission speed  1000  11ms  0.096ms at 115200bit/s
Pcm = 23 + (number of relay words + number of register words)  4
Tpc = PLC link sending time
Ttx = sending time per byte
Pcm = PLC link sending size
Ttx = 1/transmission speed  1000  11ms  0.096ms at 115200bit/s
Ltm = 13 + 2  n
Ttx = sending time per byte
Ltm = link table sending size
n = number of stations being added
The master station scan time should be confirmed using the programming
tool.
If no stations are being added, Tlk = 0.
Tlc = 10  Ttx
Ttx = 1/transmission speed  1000  11ms  0.096ms at 115200bit/s
Twt = Initial value 400ms (can be changed using SYS1 instruction)
Tls = 7  Ttx
Ttx = 1/transmission speed  1000  11ms  0.096ms at 115200bit/s
Tlc = link addition command sending time
Twt = addition waiting time
Ttx = sending time per byte
Tls = link error stop command sending time
Tso = master station scan time
