3.1Application precautions for input signals
(1)Minimum ON/OFF time of the input signal
The following conditions guarantee correct reading of the ON/OFF state of the input signal:
Input ON time: ON delay time + the time for one scan
Input OFF time: OFF delay time + the time for one scan
The ON and OFF times of the input signals must be longer than these intervals.
(2)Increasing the contact current
The reliability of some contacts cannot be guaranteed by the specified input current. In this case, install an external bleeder resistor to increase the contact current.

(4)Countermeasures against leakage current
When a switch with an LED or sensor is used, the input sometimes cannot recognize that the switch is off due to the current leakage. In this case, install a bleeder resistor to reduce input impedance.

C circuit
Select a bleeder resistor according to the following criteria:
(a)The voltage between the input terminals must be lower than the OFF voltage when the sensor is switched off.
(b)The current must be within the allowable range when the sensor is switched on.
(c)Calculate the wattage of the bleeder resistor by multiplying the current when the sensor is switched on times three.

The user program and the data stored in the EEPROM are transferred to the RAM when power is turned on. Subsequent program execution is done based on the RAM contents. Program editing is also performed on the RAM contents.
Therefore, if the program is modified, it is necessary to issue the EEPROM Write command from the programming tool. Otherwise, the modified program is over- written by original EEPROM contents when the power is turned off and on again.

Peripheral support:
Supports the communications with the programming tool or external devices connected by the computer link function. The time for this operation is limited within approx. 2 ms in the floating scan mode, and within allowable idling time in the fixed- time scan mode.
If the special relay S158 is set to ON, the peripheral support priority mode is selected. In the peripheral support priority mode, the peripheral support time is not limited. As the result, the communication response is improved although the scan time becomes long at the time.

Registers are divided into eight types:

Device and register numbers
X devices share the same memory area as XW registers. Device X004, for example, represents the number 4 bit in the XW00 register.

6.2 Index modification
When registers are used as operands of instructions, the method of directly designating the register address as shown in Example 1) below is called ???direct addressing???.
As opposed to this, the method of indirectly designating the register by combination with the contents of the index register (I, J, or K) as shown in Example 2) below is called ???indirect addressing???. In particular, in this case, since the address is modified using an index register, this is called ???index modification???.

The I/O interrupt #2 is also used with the high speed counter function. Refer to section 8.3 for details.
(3)I/O interrupt #3
The I/O interrupt #3 is used with the interrupt input function. When the state of the interrupt input is changed from OFF to ON (or ON to OFF), the I/O interrupt #3 is activated immediately with suspending other operation. The end of the I/O interrupt #3 is also recognized by the IRET instruction. For detailed information, refer to section 8.4.

The I/O interrupt #4 is also used with the interrupt input function. Refer to section 8.4 for details.
If an interrupt factor is generated while other interrupt program is executing (including the timer interrupt), the interrupt factor is held. Then it will be activated after finishing the other interrupt program execution.

Expression
Input ??? [ RST A ]??? Output
Function
When the input is ON, the device A is reset to OFF ifA is a device, or the data 0 is stored in the register A if A is a register.
Execution condition
Operand
Example 1 (device reset)
When R011 is ON, R005 is reset to OFF. The state of R025 is remained even if R011 comes OFF.
Example 2 (register reset)
When R011 is ON, the data 0 is stored in RW20. (R200 to R20F are reset to OFF) The state of RW20 is remained even if R011 comes OFF.

FUN 118 SETC Set carry
Expression
Input ??? [ SETC ]??? Output
Function
When the input is ON, the carry flag (CF = S050) is set to ON.
Execution condition
Operand
No operand is required.
Example
When R011 is changed from OFF to ON, the carry flag S050 is set to ON.

FUN 119 RSTC Reset carry
Expression
Input ??? [ RSTC ]??? Output
Function
When the input is ON, the carry flag (CF = S050) is reset to OFF.
Execution condition
Operand
No operand is required.
Example
When R010 is changed from OFF to ON, the carry flag S050 is reset to OFF.

FUN 146 STOT Step sequence output
Expression
Input ??? [ STOT A ]??????
Function
When the input is ON, the device A is set to ON and the devices of STIN instructions on the same rung are reset to OFF.
Execution condition
Operand
Example
See example on STIN (FUN 145) instruction.
Note
???The STIZ, STIN and STOT instructions are used together to configure the step sequence.
???Two or more STOT instructions can be placed on one rung to perform simultaneous sequences.
???Two or more STIN instructions can be placed on one rung in parallel or in series to perform loop or convergence of sequences. (Max. 11 STIN instructions on one rung)
???To perform the conditional branch (sequence selection), separate the rungs as follows. This limitation is applied to T1 version 1.00 only.

7. Instructions
Function
When the input is ON, the following operation is executed. (Upper limit for A by B) If A ??? B, then C = A.
If A > B, then C = B.
Execution condition
Operand
Example
When R030 is ON, the upper limit operation is executed for the data of RW018 by the data of D1200, and the result is stored in RW021.
C
(RW021) 
Upper limit B (D1200)
A (RW018)
When RW018 is 3000 and D1200 is 4000, 3000 is stored in RW021 and R0040 is OFF. When RW018 is 4500 and D1200 is 4000, the limit value 4000 is stored in RW021 and R0040 is ON.
Note
???This instruction deals with the data as signed integer

7. Instructions
Function
When the input is ON, the following operation is executed. (Lower limit for A by B) If A ??? B, then C = A.
If A < B, then C = B.
Execution condition
Operand
Example
When R031 is ON, the lower limit operation is executed for the data of RW019 by the data of D1220, and the result is stored in RW022.
C
(RW022)
A (RW019)
Lower limit B (D1220)
