1. T3H Overview

 

 

Status LEDs:

 

 

 

RUN

Lit

 

User program is being executed (RUN mode)

 

 

(green)

Blink

 

User program execution is stopped (HOLD mode)

 

 

 

Not lit

 

User program execution is stopped (HALT or ERROR mode)

 

 

FAULT

Lit

 

CPU or program error

 

 

(red)

Blink

 

Hardware initialization error

 

 

 

Not lit

 

Normal

 

 

I/O

Lit

 

I/O error

 

 

(red)

Blink

 

Hardware initialization error

 

 

 

Not lit

 

Normal

 

 

BATT

Lit

 

Battery voltage is normal

 

 

(green)

Not lit

 

Battery voltage is low (battery replacement is required)

 

 

RAM/ROM switch:

 

 

 

RAM

User program stored in RAM is used.

 

 

 

(Program transfer from EEPROM to RAM is not executed)

 

 

ROM

At the beginning of RUN mode, user program stored in EEPROM is transferred to

 

 

 

RAM. (It is called Initial load)

 

 

 

If an IC memory card which contains user program has been installed, the IC

 

 

 

memory card becomes transfer source.

 

 

 

(If mode control switch is in P-RUN, the initial load is not executed)

 

Note) In case of T3, the RAM/ROM switch has the function of auto-RUN/standby selection in addition to the initial load selection.

However, in case of T3H, the RAM/ROM switch only has the function of initial load selection as mentioned above.

Mode control switch:

HALT

User program execution is stopped. (HALT mode)

 

Normally, programming is performed in the HALT mode.

 

T3H operation mode control by programmer is not allowed.

RUN

T3H executes user program cyclically. (RUN mode)

 

It is the normal switch position under operation.

 

Even in the RUN mode, program changes are possible. However, saving into the

 

EEPROM is available only in the HALT mode.

 

T3H operation mode control by programmer is possible.

P-RUN

T3H executes user program cyclically. (RUN mode)

 

User program and the leading 4 k words of D register (D0000 to D4095) are write-

 

protected.

 

T3H operation mode control by programmer is possible.

Note) In case of T3, even in P-RUN, data writing into D0000 to D4095 by instruction is allowed except for some instructions.

However, in case of T3H, data writing into D0000 to D4095 by instruction is inhibited if in P-RUN.
