X0
SET M0
M0
DSW X10 Y10 D0 K0
RST M0
M1029
When X0 = ON, DSW will be
enabled.
When X0 = OFF, M0 is
latched. M0 will be reset
only when DSW instruction
is completed to activate
M1029.
2. Error Operation Flags
Errors occur during the execution of the instruction when the combination of application
instructions is incorrect or the devices designated by the operand exceed their range. Other
than errors, the flags listed in the table below will be On, and error codes will also appear.
3. Flags to Extend Functions
Some instructions can extend their function by using some special flags.
Example: instruction RS can switch transmission mode 8-bit and 16-bit by using M1161.
Device Explanation
M1067
D1067
D1069
When operational errors occur, M1067 = ON. D1067 displays the error code.
D1069 displays the address where the error occurs. Other errors occurring will
update the contents in D1067 and D1069. M1067 will be OFF when the error is
cleared.
M1068
D1068
When operational errors occur, M1068 = ON. D1068 displays the address
where the error occurs. Other errors occurring wil not update the content in
D1068. RST instruction is required to reset M1068 otherwise M1068 is latched.
Limitations for times of using instructions
Some instructions can only be used a certain number of times in a program. These instructions
can be modified by index registers to extend their functionality.
1. Instructions can be used once in a program:
API 60 (IST) API 155 (DABSR)
2. Instruction can be used twice in a program:
API 77 (PR)
3. Instruction can be used 8 times in a program:
API 64 (TTMR)
4. For counters C232~C242, the total max times for using DHSCS, DHSCR and DHSZ
instructions: 6. DHSZ can only be used less than 6 times.
