2-5. Check and clear cyclic communication errors

If the same device number reports the same fault 3 times in a row in cyclic communication, an error occurs. This
section describes how to check and clear this cyclic communication error.

1) When the whole address map can be used

Note 1: In the address creation step above, the program shifts the LOOP variable one bit left (2x). This is

because the address number to read increases by 2 each time the loop is executed.

Note 2: The number of loop executions will always be less than 16. This is because one read loop can obtain

the data for 4 local devices. (64 / 16 = 4)

Start

Outpw (Add, Data)

Write back the data you just read in order to clear the
change-interrupt flag.

End

Assume that the routine is started by an interrupt being
issued; INT = LOW.

Sts = Inpw (0x0000h)

Read the status data in the center device.

EIOE = 1 ?

YES

LOOP = 0

WORK = LOOP << 1
Add = 0 WORK
Data = Inpw(Add)

- Shift the loop variable 1 bit left to create the read address.
- Read the contents of the address that was just created.

Communication

error?

YES

Process specified by the user

In this step, process all the flags that are 1 (the other flags
do not need to be processed.)

Although this example checks the interrupt flags on
all the addresses by using loop processing, you can
check just the areas required.

Bit positions which are 1 correspond to device numbers
where a cyclic communication error has occurred.

Note 2

Note 1

LOOP = LOOP + 1

LOOP< 4 ?

YES
