Details
• When one of F0 to 2047 is turned on by OUT F or
SET F instruction, the F number, which has been detected earliest
among the F numbers which have turned on, is stored in BIN code.
• SD1009 can be cleared by RST F or LEDR instruction.
If another F number has been detected, the clearing of SD1009
causes the next number to be stored in SD1009.
• When operation error has occurred during execution of application
instruction, the step number, at which the error has occurred, is
stored in BIN code.
Thereafter, each time operation error occurs, the contents of
SD1010 are renewed.
• When operation error has occurred during execution of application
instruction, the step number, at which the error has occurred, is
stored in BIN code. Since the step number is stored into SD1011
when SM1011 turns from OFF to ON, the data of SD1011 is not
updated unless SM1011 is cleared by a user program.
• The I/O control mode set is returned in any of the following
numbers:
0: Both input and output in direct mode
1: Input in refresh mode, output in direct mode
3: Both input and output in refresh mode
• The operation status of CPU as shown below are stored in
SD1015.
