RS-232 serial line cable between a VT and a drive
Once the project has been transferred from the PC to the VT (ESA), the
video terminal may be connected to a single drive, hence establishing
communication via the MSP serial port of the VT and the drive's RS-232
serial port.
NOTE. When mentioning a drive, it means any model of the FAGOR
catalog, i.e. AXD, SPD, ACD, SCD, MMC and CMC models.
MANDATORY. The RS-232 serial line can only be used between the ESA
VT and a single drive. The arrow of the drive's node selecting rotary switch
(NODE SELECT) must be pointing at 0.
It is now possible to handle and control from the Video Terminal the
process application by communicating with the connected drive. The
connection cable to be used is described next.
NOTE. The adapter RS232/RS422 BE is not required in any case.
