1. Introduction

2NC

The FX

-4DA analog output block (hereafter referred to as "FX converts 4 digital values (from the PLC mai n unit) into analog o utput values (voltage or current).

2NC

The FX

-4DA can be connected to the FX

1) Each analog output channel can be con figured for voltage output, or c urrent

output. The output mode must be set using the TO instruction and the appropriate connection meth od. A different analog output can be selected for each channel .

2) The voltage output ranges from -10 to 10 V. The current output ranges from

4 to 20 mA and from 0 to 20 mA. The output cha racteristics can be adjusted for each channel.

3) The resolution is 5 mV (10 V × 1/2000) when the voltage output i s used, 20

µA (20 mA × 1/1000 ) when the current output is used.

4) Data transfer with the PLC is performed via the buffer memories of the

2NC

-4DA

-4DA by FROM/TO instructions.

[BFM #0] Output mode select

The value of BFM #0 switches the analog output between voltage and current for each channel. It takes the form of a 4 digit hexadecimal number. The first digit will be the command for channe l 1 (CH1), and the second digit for channel 2 (CH2) etc. The numeric values of these four digits respectively represent the following items :

Switching the output mode resets the I/O character istics to the factory-default characteristics. Refer to the pe rformance specifications d escribed in section 5 . Example: H2110 CH1: Voltage output (-10 V to 10 V)

[BFM #5] Data holding mode

While the programmable controller is in the STOP mode, the last output value in the RUN mode will be held. To reset the value to the offset value, write the hexadecimal value in BFM #5 as follows:

The offset and gain values ar e changed by writing new data to BFM #10 to #17. The units of the data to be written are mV or µA. T he data should be wr itten and then BFM #8 and #9 set. Note that the data value will be rounded down to the nearest 5mV or 20µ A.

[BFM #21] I/O characte ristics adjustment in hibit

Setting BFM #21 to K2 inhibits the user from inadvertent adjustment of I/O characteristics. The adjustment inhibit function, once set, will be valid until the Permit command (BFM #21= K1) is set. The initial value is K1 (Perm it). The set value will be retained even after power-OFF.

[BFM #30] Identificat ion code

The identific ation code for a special function block is read using the FROM instruction. The identification code for the FX unit can use this facility in the p rogram to identi fy the special fu nction block before commencing any data trans fers from and to the special func tion block. Note: Values of BFM #0, #5, and #21, are stored in the EEPROM memory of the

2NC

-4DA. BFM #10 to #17 are copied to EEPROM when the gain/offset setting command BFM #8, #9 is used. Also, BFM #20 causes the resetting of the EEPROM memory. The EEPROM has a life of about 10,000 cycles (changes), so do not use programs which frequent ly change these BFMs. A mode change of BFM #0 automatically involves a c hange of the corresponding offset and gain values. Because of the time needed to write the new values to the internal EEPROM memo ry, a delay of 3 s is required between instructions changing BFM #0 and instructions writing to the cor responding BFM #10 through BFM #17. Therefore, a delay timer should be used before writin g to BFM #10 through #17. (Refer to chapter 9.)

7. Operation and Program Examples

If the factory-default I/ O characteristics ar e not changed and the status information is not us ed, you can operate the FX simple program. For the FROM and TO instructions, refer to the FX Programming Manual (II). CH1 and CH2 : Vol tage output mode (-10 V to 10 V) CH3 : Current output mode (4 mA to 20 mA) CH4 : Current output mode (0 mA to 20 mA)

7.1 Operation proced ure

1) Tur n OFF the power of the PLC, and then connect the FX wards, wire the I/O lines of the FX

2) Set the PLC to STOP, and turn O N the power. Write the above program then switch the PLC to RUN.

3) Analog values will be sent from D0 (BFM #1), D1 (BFM #2), D2 (BFM #3), and D3 (BFM #4) to the respective output channels of the FX 4DA. When the PLC is in STOP, the analog values set before stopping the PLC will remain output . (The output will be hel d.)

4) When the PLC is in STOP, the offset values can also be output. For a detailed description, refer to Section 6).

7.2 Program example

In the example shown below, CH1 and CH2 in the FX to the special function block No. 0, are handled as the voltage ou tput, CH3 is handled as the current output (4 to 20 mA), CH4 is handled as the current output (0 to 20 mA), and these outputs are held when the PLC is stopped. In the example shown below, the status information is utilized.

2) The FX Confirm that the total value inc luding the 5V curr ent consumption of other special function blocks is less than the limit.

3) The FX Make such a program that changes over the output of the BF M #0 before writing the output d ata.

4) After the 24V DC power for the FX analog output may fluctuate for approximately 1 second. This is due to time delays in the power supply fr om the main unit or differences in start time. For this reason, be sure to take preventive measures so that this output fluctuation will not affect the external units.
