6.9 On-line debug support functions
The following on-line (during RUN) f un c tions are suppor ted in the T1-16S for effective
program debugging.
On-line function 4 k mode 8 k mode
Force function Yes Yes
Sampling trace functi on Yes Yes
Changing timer /counter
preset value Yes Yes
Changing constant operand of
function instruction Yes Yes
Changing device dire ctly Yes Yes
Program changing in edi t
mode Yes No
EEPROM write command Yes Yes
Refer to section 6.5 for 4 k/8 k mode.
Force function
Two types of force functions are available, input force and coil force.
The input force is used to disable the external input signals. When an external input
device is designated as forced input, the ON/OFF state of the device can be changed
manually by using the data setting function of the programming tool, regardless of the
corresponding external signal state. The input force designation is available for the
external input devices (X).
The coil force is used to disable the coil instruction. When a coil instruction on the
program is designated as forced coil, the ON/OFF state of the coil device can be
changed manually by using the data setting function of the programming tool,
regardless of the coil circuit execution status.
On the programming tool, the forced input and forced coil are expressed as follows.
Forced input
ForcedNormal
X005 x005
Forced coil
ForcedNormal
Y023 Y023
If EEPROM write operation is executed with remaining the force
designation, the force designation is also saved into the built-in EEPROM.
Because the force function is debugging function, release all force
designation before executing the EEPROM write operation. The force batch
release command is available when the T1-16S is in HALT mode.
