Publication 1756-IN566D-EN-P - June 2008
85 During runtime, the data size sent
by the slave device does not match
the size in the corresponding scan
list entry. Since variable length poll data is not
supported, verify that the slave device is
functioning properly.
86 The device is in Idle mode, or not
producing data, while the scanner is
in Run mode. • Check the configuration and status of
the device.
• If you set up an interlock between 2
scanners (controllers), make sure
both scanners are in Run mode.
87 Scanner cannot listen to shared
inputs from slave device because
the owning scanner has not
established communication with
that slave device. • Verify primary scanner connection
and configuration.
• Verify that the slave device is
producing data.
88 Scanner cannot listen to shared
inputs from slave device because
I/O parameters (for example, polled
or strobed, electronic key, data size)
for that slave device are configured
differently between this scanner
and the owning scanner. In this scanner, reconfigure the I/O
parameters for the shared inputs scan list
entry so that they match those same
parameters in the owning scanner.
89 Scanner failed to configure a device
using the Automatic Device
Recovery (ADR) parameters.
• Make sure that you installed a
compatible device.
• If the offline configuration of the
device does not match the actual
(online) configuration of the device,
change the offline configuration to
match the online configuration.
90 Controller has set the scanner to
the Disabled mode. If desired, enable the scanner by locating
the O.CommandRegister.DisableNetwork
bit on the command register and turning it
off.
