IBM download scheme for GWY-00 models:
Gateway needs Firmware, Project and TWO drivers to communicate with two devices. Firmware is factory
programmed. If both or one of the drivers has not been downloaded in Gateway, Gateway permanently waits
for IBM download (indicated by continuous blinking of the OK LED).
Create project as per system requirements. Select PLC1 Driver, PLC2 Driver and Project for downloading.
GWY-00 can be configured by following method.
1. If both the drivers are downloaded, at power up Gateway polls for PLC1 / COM1 device (OK LED
steady on max upto 5 seconds). If no device is found on this port, Gateway waits for IBM download
on either of the ports (OK LED blinking for 10 seconds). If IBM download is not established,
Gateway will again poll for PLC1 / COM1 device. This sequence continues till either of the
communication is established.
2. If communication with PLC1 / COM1 device is established, Gateway tries to connect with
PLC2 / COM2 device. If this communication is not successful, Gateway polls for IBM download.
Same sequence explained in 1 will be followed, this time for PLC2 / COM2 and IBM.
3. If Gateway has established communication with both the devices, user must first disconnect one of
the device to configure Gateway.
4. Connect IBM download cable on any of the ports.
5. Download PLC1 / COM1 driver, PLC2 / COM2 driver and Project.

Software will ask user if the Gateway has to be reset. Gateway must be reset unless user wants to
download setup again.
IMPORTANT:
1.
When user wants to establish IBM communication on one port, communication on the other
port should not interrupt IBM communication. It is advised that communication on the other
port be stopped to ensure error free IBM communication.
IBM download scheme for GWY-00 models with Bootblock version 2.00A :
Use Software version 2.00A. Setup can be downloaded on PLC1/ Com1 port only. Create project as per
system requirements. Select PLC1 Driver, PLC2 Driver and Project for downloading. GWY-00 can be
configured by either of the following two methods:
METHOD I
1.
Connect configuration Cable and power cables to GWY-00.
2. Apply power to GWY-00.
3. Download PLC1 driver, PLC2 driver and project within 10 seconds after power-on.
METHOD II
1.
Short pins 3 and 4 on PLC1 port of GWY-00 for at least 1 second after power-on. Remove the short.
Now GWY-00 permanently waits for IBM download. Connect IBM download cable.
2. Download PLC1 driver, PLC2 driver and project.
The unit will automatically return to normal operation mode after a download cycle. If the user wants to
perform another download user has to bring the unit back into configuration mode using Method I or
Method II.
