, where <value1>~<value5> can have a value between 0 and 3 as below:
DIO Synchronization Configuration
0 Disabled
1 Synchronization Input
2 Synchronization Output
3 Synchronization Input/Synchronization Output
The output status of a DIO output pin with Synchronization Output at one device changes
according to the DIO input status of corresponding DIO input pin with Synchronization Input at
the other device. A DIO output pin with Synchronization Input/Synchronization Output can be
used as Synchronization Input or Synchronization Output.
“1 Synchronization Input” and “2 Synchronization Output” is explained at 5.4.1 Input/Output
Synchronization in detail.
“3 Synchronization Input/Synchronization Output” is described at 5.4.2
Output/Output Synchronization in detail.

* Changes of DIO Synchronization configuration are applied without rebooting.
5.4.1. Input/Output Synchronization
The Input/Output Synchronization means the synchronization between two Parani-BCD110V3s
which are connected on I/O profile - one is set as Digital Input for I/O configuration and the other
is set as Digital Output.
For example, let’s assume that there are two Parani-BCD110V3s connected on I/O profile which
are BCD1 and BCD2. The DIO1 of BCD1 is set as Digital Input for I/O configuration and
Synchronization Input for DIO Synchronization Configuration. The DIO1 of BCD2 is set as Digital
Output for I/O Configuration and Synchronization Output for DIO Synchronization Configuration.
When DIO1 status of BCD1 changes, DIO1 status of BCD2 is synchronized as to DIO1 status of
BCD1.
5.4.2. Output/Output Synchronization
The Output/Output Synchronization means the synchronization between two Parani-BCD110V3s
which are connected on I/O profile and whose I/O configuration are Digital Output.
For example, let’s assume that there are two Parani-BCD110V3s connected on I/O profile which
are BCD1 and BCD2. The DIO1 of BCD1 is set as Digital Output for I/O Configuration and
