1. Introduction
The FX
2NC
-4DA analog output block (hereafter referred to as "FX
2NC
-4DA")
converts 4 digital values (from the PLC main unit) into analog output values
(voltage or current).
The FX
2NC
-4DA can be connected to the FX
2NC
Series PLC.
1) Each analog output channel can be configured for voltage output, or current
output. The output mode must be set using the TO instruction and the
appropriate connection method.
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 characteristics can be adjusted
for each channel.
3) The resolution is 5 mV (10 V × 1/2000) when the voltage output is 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
FX
2NC
-4DA by FROM/TO instructions.

6. Buffer Memory (BFM)
The FX
2NC
-4DA exchanges data with the PLC via the buffer memory addresses
(16-bit data) in the FX
2NC
-4DA.
BFM #0 to #5, #8 to #17, #20 and #21 can be written by the PLC using the TO
instruction. BFM #29 and #30 can be read using the FROM instruction.
6.1 Buffer Memories (BFM) lists
*1 The status of BFM #0, #5, and #21, will be written to EEPROM, therefore the
set values will be retained even after turning OFF the power.
*2 Offset data:Actual analog output value when corresponding output data (BFM
#1 to #4) is 0
*3 Gain data: Actual analog output value when corresponding output data (BFM
#1 to #4) is 1,000
*4 When current output mode 1 (4 mA to 20 mA) is set, the offset data will be
automatically set to 4,000 and the gain data to 20,000. When the current output
mode 2 (0 mA to 20 mA) is set, the offset data will be automatically set to 0 and
the gain data to 20,000.
[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 channel 1 (CH1), and the second digit for channel
2 (CH2) etc. The numeric values of these four digits respectively represent the
following items:
O = 0:Sets the voltage output mode (-10 V to 10 V).
O = 1:Sets the current output mode (4 mA to 20 mA).
O = 2:Sets the current output mode (0 mA to 20 mA).
Switching the output mode resets the I/O characteristics to the factory-default
characteristics. Refer to the performance specifications described in section 5.
Example: H2110CH1: Voltage output (-10 V to 10 V)
CH2 and CH3: Current output (4 mA to 20 mA)
CH4: Current output (0 mA to 20 mA)
[BFM #1, #2, #3 and #4] Output data channels CH1, CH2, CH3, and CH4
BFM #1: Output data of CH1 (Initial value: 0)
BFM #2: Output data of CH2 (Initial value: 0)
BFM #3: Output data of CH3 (Initial value: 0)
BFM #4: Output data of CH4 (Initial value: 0)
[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:
O = 0: Holds the output.
O = 1: Resets to the offset value.
Example: H0011 CH1 and CH2 = Offset value CH3 and CH4 = Output holding

[BFM #8 and #9] Offset/gain setting command
Changes offset and gain values of channels CH1 to CH4 by writing 1 to the
corresponding Hex digits of BFM #8 or #9. The current values will be valid until
this command is output. (Refer to Chapter 9)
1 to 4: Channel number O = 0: No changes done. O = 1: Change data value.
[BFM #10 to #17] Offset/gain data
The offset and gain values are changed by writing new data to BFM #10 to #17.
The units of the data to be written are mV or µA. The data should be written and
then BFM #8 and #9 set. Note that the data value will be rounded down to the
nearest 5mV or 20µA.
[BFM #20] Initialize
When K1 is written in BFM #20, all values will be returned to the factory-default.
(Note that the BFM #20 data will override the BFM #21 data.)
This initialize function is convenient if you have an error in adjustment.
[BFM #21] I/O characteristics adjustment inhibit
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 (Permit). The set
value will be retained even after power-OFF.
[BFM #29] Error status
When an error occurs, use the FROM command to read out the details of the
error.
Error status
Bits b4 to b9, b11, b13 to b15 are not defined.
[BFM #30] Identification code
The identification code for a special function block is read using the FROM
instruction. The identification code for the FX
2NC
-4DA unit is K3020.The main
unit can use this facility in the program to identify the special function block
before commencing any data transfers from and to the special function block.
Note:
Values of BFM #0, #5, and #21, are stored in the EEPROM memory of the
FX
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 frequently change these BFMs.
A mode change of BFM #0 automatically involves a change of the
corresponding offset and gain values. Because of the time needed to write the
new values to the internal EEPROM memory, a delay of 3 s is required between
instructions changing BFM #0 and instructions writing to the corresponding
BFM #10 through BFM #17.
Therefore, a delay timer should be used before writing to BFM #10 through #17.

7. Operation and Program Examples
If the factory-default I/O characteristics are not changed and the status
information is not used, you can operate the FX
2NC
-4DA using the following
simple program. For the FROM and TO instructions, refer to the FX
Programming Manual (II).
CH1 and CH2: Voltage 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 procedure
1) Turn OFF the power of the PLC, and then connect the FX
2NC
-4DA. After
wards, wire the I/O lines of the FX
2NC
-4DA.
2) Set the PLC to STOP, and turn ON 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
2NC
-
4DA. When the PLC is in STOP, the analog values set before stopping
the PLC will remain output. (The output will be held.)
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
2NC
-4DA, connected
to the special function block No. 0, are handled as the voltage output, 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.
8. Caution Regarding Operation
1) Check whether the output wiring and/or the FX
2NC
-4DA is properly
connected to the FX
2NC
main unit.
2) The FX
2NC
-4DA uses 30mA (5V) supplied from the main unit.
Confirm that the total value including the 5V current consumption of
other special function blocks is less than the limit.
3) The FX
2NC
-4DA starts operation when the 24V DC power is set to ON.
Make such a program that changes over the output of the BFM #0
before writing the output data.
4) After the 24V DC power for the FX
2NC
-4DA is turned ON or OFF, the
analog output may fluctuate for approximately 1 second. This is due to
time delays in the power supply from 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.
