12-2. SI/FII High Speed Bi-Directional 2- Wire Serial Interface
SF/FII is a high speed bi-directional serial interface for connecting F805AT-CK to various peripheral
Devices. These include printers, remote displays, converters (D/A, BCD-IN, BCD-OUT, RS-232C) as
well as PLC’s (Mitsubishi
CC-Link, Omron CompoBus/D, Yokogawa FAM3, Allen-Bradley Open
DeviceNet).
Up to 20 devices may be connected by 2-core parallel or shielded cable with polarity.
●
Connection
In this network up to 4 weighing controllers (specified by different ID numbers) are connected by
SI/FII positive to positive, negative to negative.
The M350 printer serves up to 4 coded simultaneous sources, in one of 32 statistical categories. The
LD517 remote display accumulates or sums up to 4 coded simultaneous sources.
Our converters (E924, E928, E930, E232) allow the 4 coded sources to communicate with PC
’
s or
PLC

s.
●
Auto print command
The F805AT-CK gives an automatic print command to any device connected by SI/F interface.
In Simple Comparison Mode the automatic print command is sent when the Complete output signal
turns ON. In Sequence with Judgement the automatic print command is sent when judgement output
signals (Over, Go, Under) turn ON. In sequence without Judgement the automatic print command
cannot be sent out.
Also, when weighing result exceeds 99999, the automatic print command can not be sent out.
