FX2N-5A Special function block Buffer Memory (BFM) 7
7-14
7.2.2 BFM 1 output mode specification (READ/WRITE)
BFM 1 specifies the output mode of the analog output CH1. The BFM consists of a 4-digit
hexadecimal code, where only the lowest digit is assigned to the analog output channel. The
range for the digit is a Hex value between 0 to A.
The highest 3 digits are simply ignored by the module, whereas the lowest digit corresponds to
output ch1.
The meaning of the digits is as follows:
0: Voltage output mode (-10 to +10 V) (output range -32000 to +32000)
1: Voltage output mode (-10 to +10 V) (output range -2000 to +2000)
2: Current output mode (4 to 20 mA) (output range 0 to 32000)
3: Current output mode (4 to 20 mA) (output range 0 to 1000)
4: Current output mode (0 to 20 mA) (output range 0 to 32000)
5: Current output mode (0 to 20 mA) (output range 0 to 1000)
6: Absolute Voltage output mode (-10 to +10 V) (output range -10000 to +10000)
7: Absolute Current output mode (4 to 20mA) (output range 4000 to 20000)
8: Absolute Current output mode (0 to 20mA) (output range 0 to 20000)
9: Scaling Voltage output mode (-10 to +10 V) (maximum output range -32768 to +32767)
A: Scaling Current output mode (0 to 20 mA) (maximum output range 0 to 32767)
B to F: not valid; the module will automatically restore the last valid setting.
