Proline Promag H 500 PROFIBUS DP Diagnostics and troubleshooting
Hauser 159
For output signals
Error Possible causes Solution
Signal output outside the valid
range Main electronics module is
defective. Order spare part →  202.
Device shows correct value on local
display, but signal output is
incorrect, though in the valid range. Configuration error Check and correct the parameter
configuration.
Device measures incorrectly. Configuration error or device is
operated outside the application. 1. Check and correct parameter
configuration.
2. Observe limit values specified in
the "Technical Data".
For access
Error Possible causes Solution
No write access to parameters Hardware write protection enabled Set the write protection switch on
main electronics module to the
OFF
position →  146.
No write access to parameters Current user role has limited access
authorization 1. Check user role →  77.
2. Enter correct customer-specific
access code →  77.
No connection via PROFIBUS DP PROFIBUS DP bus cable connected
incorrectly Check terminal assignment
→  39.
No connection via PROFIBUS DP PROFIBUS DP cable incorrectly
terminated Check terminating resistor .
Not connecting to Web server Web server disabled Using the "FieldCare" or "DeviceCare"
operating tool, check whether the
Web server of the measuring device
is enabled, and enable it if
necessary→  84.
Incorrect setting for the Ethernet
interface of the computer 1. Check the properties of the
Internet protocol (TCP/IP) →  80.
2. Check the network settings with
the IT manager.
Not connecting to Web server Incorrect IP address Check the IP address:
192.168.1.212 →  80
Not connecting to Web server Incorrect WLAN access data • Check WLAN network status.
• Log on to the device again using
WLAN access data.
• Verify that WLAN is enabled on
the measuring device and
operating device .
WLAN communication disabled –
Not connecting to Web server,
FieldCare or DeviceCare No WLAN network available • Check if WLAN reception is
present: LED on display module
is lit blue
• Check if WLAN connection is
enabled: LED on display module
flashes blue
• Switch on instrument function.
Network connection not present or
unstable WLAN network is weak. • Operating device is outside of
reception range: Check network
status on operating device.
• To improve network
performance, use an external
WLAN antenna.
Parallel WLAN and Ethernet
communication • Check network settings.
• Temporarily enable only the
WLAN as an interface.
