*Standard mode (4bytes inputs + 4 bytes outpus)
**Special mode (6 bytes inputs + 4 bytes outputs)
EX240 Special Mode Setting:
This mode can be set using the DIP switch accessible from right side of EX240
serial unit. With the switch position to "1" (on), the serial unit can
communicate continuously regardless of solenoid power condition (with the
switch set to "0" (off), the serial unit will lose communication if the
solenoid power falls below specifications). The default DIP switch setting is
all bits OFF. In this special mode setting, the serial unit can notify the PLC
of the solenoid valve power state and input unit over-current status (via input
data). However, special configuration is required: configure your system for 6
bytes inputs and 4 byte outputs instead of 4 bytes / 4 bytes. This makes it
possible to monitor solenoid valve power state (3rd bit) and input over-current
state (4th bit) in the sixth byte of the input register.
