System Configuration and Setup 4-101
Table 4-15 Conveyor Configuration Options (MPC555) – Upstream/Downstream Settings
Feature Description
Upstream
Mode
:
 SMEMA - SMEMA handshaking to load boards automatically.
 Manual Load - Load boards by hand.
Ready Output
: Standard SMEMA handshaking signals.
 Output No. – Select the appropriate output number. See FmXP Online Help.
 Assertion Level
 High = When the bit is high, the device is ON.
 Low = When the bit is low, the device is ON.
Available Input
: Standard SMEMA handshaking signals.
 Input No. – Select the appropriate input number. See FmXP Online Help.
 Assertion Level
 High = When the bit is high, the device is ON.
 Low = When the bit is low, the device is ON.
Handshake Timeout
: The amount of time expected for a board to enter the dispensing
system from an upstream system once SMEMA handshaking has begun.
Example:
The dispensing system sends a "Ready for a board" signal to the upstream system. The
upstream system responds with a "Board available" signal. The dispensing system
waits for the time designated in Handshake Timeout for the board to enter the
dispensing system. If the timeout expires before a change in the signal occurs, an error
is issued.
Downstream
Mode
:
 SMEMA = SMEMA handshaking to unload boards automatically
 Manual Unload = unload boards by hand
 No Handshake = Unloads boards automatically without using SMEMA
handshaking
Ready Input
: Standard SMEMA handshaking signals.
 Output No.: Select the input number from (TBD)
 Assertion Level:
 High = When the bit is high, the device is ON.
 Low = When the bit is low, the device is ON.
Available Output
: Standard SMEMA handshaking signals.
 Output No.: Select the output number from (TBD)
 Assertion Level:
 High = When the bit is high, the device is ON.
 Low = When the bit is low, the device is ON.
Handshake Timeout
: The amount of time expected for a board to be detected by a
downstream system once SMEMA handshaking has begun.
Example:
The dispensing system sends a "Board available" signal to the downstream system.
The downstream system responds with a "Ready for a board" signal. The dispensing
system waits for the time designated in Handshake Timeout for the downstream system
to lower the SMEMA "Ready" signal. If the timeout expires before a change in the signal
occurs, an error is issued.
Exit Boost
: Used only by the last heat station. It is the distance the board is moved after
the board sensor has stopped seeing the board. This is useful in case the downstream
system does not communicate with SMEMA.
