8.2.9 The Display shows an 'I'
The display 'I'dle indicator means that there is no core program executing in the S200 Position
Node. There are two ways that this can happen: Switch S13-4 is down or an error occurred in the
firmware download. If S13-4 is in the correct position then please contact customer support for
further instructions.
8.2.10 Firmware Will Not Load
S200 OC Tools version 2.0.0 has a known shortcoming where the Firmware Download code
initializes the COM port to 38,400 Baud. This problem is most likely to occur as a result of a Baud
Rate change in the drive. You must reset the drive (RS232.BAUDRATE) to 38400, do an NV
Save and power cycle the drive.
Also, GUI Versions up to and including 2.0.x will not support firmware download fro a drive whose
root directory is write-protected. To overcome this, place the firmware to be downloaded on the
local hard drive.
8.2.11 Communication 'MNS' LED is Red
The MNS LED becomes a steady red when a DeviceNet unit (-DNS Suffix) is not connected to an
active DeviceNet bus.
8.2.12 GUI Reports 'Communication Lost'
This problem exhibited itself with S200 OC Tools prior to version 2.0.0. Please go to
Danahermotion.com and download a newer version.
8.2.13 I/O Is not functioning
The Status screen on the GUI has emulated LEDs showing the status of each input and can be
used to debug I/O wiring. An external supply voltage is required and the inputs must see current
flow to be on. Check field wiring.
8.2.14 Scope Traces seem incorrect
GUI Versions up to, and including, 2.0.0 plot independent 'Y' Axis variables. We have had issues
with some customers miss-interpreting the data due to multiple Y-axis scales.
8.2.15 System is Noisy
Although this problem can occur as the result of tuning the gains too high the S200 Position Node
does exhibit some current loop hash noise. This is normal and does not affect operation. Check
user-settable gains.
8.2.16 Fault Output does not capture all faults
This shortcoming existed in firmware versions prior to 2.0.0. Please upgrade the firmware.
