Message
Code
[15:8]
Data Field
[7:0]
Description
35 01 Radio Device (polling/heartbeat) Timeout. (Decimal value 13569.) A Node is
determined to be out of the wireless network based on the parameters defined for
polling or heartbeat. See the documentation in the UCT for polling or heartbeat
parameters and the timeout operation. When the least significant bit is on (1), an
error condition exists.
• Run site survey to determine the quality of the RF link. If no communications
exist between the Gateway and Node, verify the power at the Node and all
antenna connections. The blocking of RF communications may also be a result
of environmental conditions that may have changed.
• The battery of a battery powered Node may need to be replaced. Although
the LCD and device may appear functional, the battery may not have enough
capacity to handle the current requirements of RF communications.
36 01 Modbus time-out. A Gateway timeout (time of inactivity on the serial channel) was
detected. (Decimal value 13825.) When the least significant bit is on (1), an error
condition exists.
FE -- Modbus register 8 device messages are disabled. The Modbus register 8 clears or
disables messages using the Gateway’s Modbus register 15. (Decimal values 65024
through 65279.)
9.3 Web Page Configuration
Problem Solution
No Web Page Access The IP address is wrong. The device defaults to 192.168.0.1 and the host system
should be set to 192.168.0.x. If the IP addresses were changed from the default
settings, verify the first three sections of the address are the same for both the devices
and the host.
Check the proxy settings on the browser. (See Appendix A).
When the devices are attached directly to a computer without using a hub or switch,
use a crossover cable. When using a hub or switch, use a straight cable.
After changing the IP address to the Gateway Pro or Ethernet Bridge, cycle the power
to the device to activate the change.
Unknown IP Address The device’s default IP address is 192.168.0.1. The host should be set to 192.168.0.2.
If another address is used, write it down or print out the set-up page and store in a
safe place. If the IP address of the device was changed and is unknown, follow the
Restoring Factory Default Settings instructions.
9.4 Host Link Failure
A host link failure occurs when the defined timeout period, typically set to four seconds, has elapsed with no
communications between the host system (or Modbus master device) and the Gateway.
The Gateway places an error code in its I/O 8 register and sends a message to all relevant Nodes within the system to set
outputs to the user-defined default states. Each Node has an enable flag for a host link failure condition. If a Node’s ‘host
link failure’ flag is not set, the outputs on the Node are not affected.
In the example shown, a host link failure between the host system and Gateway result in the outputs of Node 1 and Node
2 sent to the defined conditions if both Nodes have the host link failure checkbox selected.
