6. Programming Information

Timer/counter preset value (constant data) changing

The preset value (constant data) of timer or counter instruction can be changed in on-line (during RUN) by using the programming tool.

Function instruction constant operand changing (T1S only)

The constant operand of function instruction can be changed in on-line (during RUN) by using the programming tool.

Device changing (T1S only)

The device of contact or coil instruction can be changed in on-line (during RUN) by using the programming tool.

On-line program changing (T1S only)

When the T1S’s memory mode is 4 k mode, the program can be changed using normal edit mode. (rung by rung)

In the on-line program changing, it is not allowed to change the number or order of the following instructions.

END, MCS, MCR, JCS, JCR, FOR, NEXT, CALL, SUBR, RET, IRET

NOTE

The above on-line functions are performed on the RAM memory. Therefore, when program has been changed, execute the EEPROM write operation before turning off power. Otherwise, program stored in the EEPROM will be overwritten.

On-line EEPROM write (T1S only)

The EEPROM write is possible in on-line (during RUN) as well as in HALT mode. In the on-line EEPROM write, user data is not written into the EEPROM.

During this operation, the T1S’s scan time becomes longer. However, as it has the time limit per scan, the T1S’s control operation is not stopped.

NOTE

In case of the standard T1, the EEPROM write is possible only in the HALT mode.
