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.
It is now possible to handle and control from the Video Terminal the pro-
cess application by communicating with the connected drive. The connec-
tion cable to be used is described next.
The connection cable has the following connectors at its ends:
The connection is:
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.
NOTE. The adapter RS232/RS422 BE is not required in any case.
