INITIAL PLC START-UP
Lamp display:
1.
2.
When power is on, POWER LED will be lit and ERROR LED will be lit for 0.5 second.
Normal run: POWER LED should be lit and ERROR LED should turn off. When power
supply is lower than 19.5V, ERROR LED will blink continuously till the power supply goes
higher than 19.5V.
When it connects to PLC MPU in series, RUN LED on MPU will be lit and A/D LED or D/A
LED should blink.
After receiving the first RS-485 instruction during controlling by RS-485, A/D LED or D/A
LED should blink.
After converting, ERROR LED should blink if input or output exceeds upper bound or lower
than lower bound.

(CH2, CH4)= mode 3.
z
Set the number of times for average of CH1 and CH2 are K32.
z
Read the input signal average value of CH1~CH4 (4 data) and saved into D20~D23.

The rule of instruction operand:
m1: arrangement number of special module. The number of special module
that connects to PLC MPU. The numbering order of special module from the
near to the distant of MPU is from 0 to 7. The maximum is 8 special modules
and won’t occupy I/O point.
m2: the number of CR. Built in 16-bit of 49 groups memory of special module
is called CR (Control Register). The number of CR uses decimal digital
(#0~#48). All running status and setting values of special module has
included.
If using FROM/TO instruction, the unit of read/write of CR is one number for
one time. If using DFROM/DTO instruction, the unit of read/write of CR is two
numbers in one time.

16-bit command when n=6
In ES series models, flag M1083 is not provided. When FROM/TO instruction is
executed, all interrupts (including external or internal interrupt subroutines) will be
disabled. All interrupts will be executed after completing FROM/TO instruction.
Besides, FROM/TO instruction also can be executed in the interrupt subroutine.
The function of the flag M1083 (FROM/TO mode exchange) provided in EP/EH
series models:
a.
When M1083=Off, all interrupts (including external or internal interrupt
subroutines) will be disabled when FROM/TO instruction is executed. The
Interrupts will resumed after FROM/TO instruction complete. Please be
advised FROM/TO instruction can be executed in the interrupt subroutine.
b.
When M1083=On, if an interrupt enable occurs while FROM/TO
instruction are executing, the interrupt FROM/TO instruction will be
blocked till the requested interrupt finish. Unlike M1080 off situation,
FROM/TO instruction cannot be executed in the interrupt subroutine.
