SECS Communication
a
Default: 0.
SORT MODE (ECID 16)
Send or receive or both. The choice of this item does not affect the VersaPort.
MIN WAFER POS (ECID 32)
Default value for the beginning of wafer number one position (reference: bottom of port
plate).
Default: 3100 mils.
STAGE POS (ECID 33)
In response to a go to stage command from the Host, the VersaPort uses this
configuration data to lift the Pod top to expose a cassette so that a Z-axis moving robot
can pick and place wafers into and out of the cassette. The default value is also the
maximum acceptable value.
Default: 11350 mils.
SLOT COUNT (ECID 34)
This is the number of slots in the cassette (typically 25), with a maximum of 30 slots.
Default: 25.
SLOT PITCH (ECID 35)
This is the pitch from slot-to-slot in a cassette, which is the distance between the center of
one slot to the center of an adjacent slot.
Default: 250 mils.
SINGLE PORT (ECID 37)
This option allows the Host to combine the control of the motion function and
SMART-Traveler System material tracking through a single RS-232 port. Normally (with
the Single Port option set to value 0), the motion function is controlled through the Host
port, while the STS function is controlled through the MSC port. With this option set to
value 1, all communication between the Host and the VersaPort (for both motion control
and SMART-Tag information access) are consolidated to the HOST port.
0: MSC port -- access STS commands/reports such as RCS (S2,F21) and Smart Tag
8200 read/write commands.
Host port -- access HCS (S2,F41) commands/reports.
ASCII port – Standard ASCII commands and protocol.
1: MSC port -- not supported.
Host port -- access HCS (S2,F41), STS commands/reports such as RCS (S2,F21) and
Smart Tag 8200 read/write commands.
ASCII port – Standard ASCII commands and protocol.
2: MSC port -- read/write Smart Tag 8200 only, with either 3-wire or 5-wire RS232 cable.
Host port -- access HCS (S2,F41) commands/reports.
