is in the specified input range. Before inputting the value, therefore, consider the maximum error.
*1 Compatible with models that have revision “PV: 03 RL: 07 SV: 1.2”. Please refer to “Revision” on page 5.
*2 Compatible with models that have revision “PV: 04 RL: 08 SV: 2.0”. Please refer to “Revision” on page 5.
*3 The 12-bit data (0 to 4095) processed in the Analog I/O module can be linear converted to a value
between -32768 and 32767. The optional range designation and analog I/O data minimum and maximum
values can be selected using data registers allocated to analog I/O modules.
