Multiple CPU system
When a recording trigger is satisfied in a recording device, a co-recording trigger is sent to other recording devices on the
same base unit via a trigger relay device (CPU module) controlling each recording device.

: A recording trigger is satisfied.
: A co-recording trigger is sent.
: Saved data
(1) Trigger relay device (programmable controller CPU No.1)/recording device controlled by CPU No.1
(2) Trigger relay device (programmable controller CPU No.2)/recording device controlled by CPU No.2
(3) Trigger relay device (motion CPU No.3)
A trigger is also sent from a trigger relay device to a recording device in which a recording trigger is satisfied.
For the operation when a trigger satisfied in a recording device is received in the recording device itself, refer
to the manual for each recording device.
System via a network
When a recording trigger is satisfied in a recording device, a co-recording trigger is sent to a recording device in the network
destination via trigger relay devices (CPU module and network module).
