Changes
●
The replacement sequence CPU module has an Ethernet port.
●
F3SP7□-□S has no RS-232C port. If a touch panel etc. was
connected via RS-232C, it is necessary to switch to Ethernet or
go via a PC link module.
●
Dedicated ROM pack for program backup has been substituted by
a general-purpose SD card, which can also be used to store
device data.
