| <Figure 1> Read setting example of SEC Standard UPS |
Device part of <Figure 1> input Com Port(COM1), Com Baud(19200), Parity Bit(0), Data Bit(8), Stop Bit(1) respectively, according to controller. (In case of using Ethernet, input Connection Type(TCP/IP), IP address of PLC(192.168.1.70), TCP service port(6001), respectively)
Also, you can input whether to use CRC(0 = Not use, 1 = Use, Default : 0) of protocol as 0 or 1, Option part.
But, in case of setting as CRC use(1), send the AP0 command first, before communication.

Digital Write
You can change the status value of SEC Standard UPS by using digital write.
Digital write setting parameters are as follows :
PORT Connected PORT number 0 ~ 255
STATION Don't care
ADDRESS Don't care
EXTRA1 Setting command ATR (Auto Reboot : Refer to <Table 3>),
NOM(Refer to <Table 5> – Write output data to NOM_DATA.???(??? = port no) in SCAN Server Directory of Work Directory, such as in order of <Table 5>),
PSD(Shutdown action : -1 – abort, 0 – immediate, 1 >= - seconds until shutdown),
RWD(Shutdown type : seconds), SDA(Refer to <Table 7>),
STD(Startup after delay : -1 – abort, 0 – immediate, 1 >= - seconds until startup),
TST(Test : -1 – Abort Test, 0 – No Effect, 1 – General Test, 2 – Battery Test, 3 – Deep Test),
UBR(UPS Baud Rate : 1200, 2400, 4800, 9600, 19200),
UID(Sets UPS ID String : Max 64 letters, Write UPS ID to UID_DATA.??? (??? = port no) in SCAN Server Directory of Work Directory),
CN1 (Rectifier ON/OFF : 1 = ON, 0 = OFF),
CN2 (Inverter ON/OFF : 1 = ON, 0 = OFF),
CN3 (Static ON/OFF : 1 = ON, 0 = OFF),
AP0 (Command for using CRC check : 1 = In case of AP0 command, CRC is included, 0 = In case of AP0 command, CRC isn't included),
EXTRA2 Don't care
Write example 1)
Port : 0, Extra1 : ATR
If you set as above and write digital value, you can change(ON/OFF) Auto Reboot status value of SEC Standard UPS.
Analog Write
Analog write and digital write have the same settings, but output value is only different.
