19 SWITCHING THE MODE AFTER STARTING
19.3 I/O Signals for Handshake with CPU Module and Buffer Memory
*2 It indicates the setting value for the communication speed.
• Set "80H" to the interface to which "MELSOFT connection" is set for the switching mode No. designation. The
communication speed set on the Engineering tool side is applied.
The following I/O signals for handshake and buffer memories need to be considered on the CPU module side at the time of
mode switching from the target device.
•'CH switching mode' (X6/XD)
• 'Parameter setting error, mode switching error status' (Un\G515)
