6.2.2 I/O Point

If you are experiencing troubles with an I/O point (Analog Input, Analog

Output, Discrete Input, Discrete Output, Pulse Input, RTD Input, or

Thermocouple Input):



Check (using ROCLINK 800 software) to see how the channel is

configured.



If the configuration looks correct, then follow the procedure for

troubleshooting that type of I/O (refer to

Chapter 6



If a module does not function correctly, determine if the problem is

with the field device or the module.



Check a module suspected of being faulty for a short circuit between

its input or output terminals. If a terminal not directly connected to

ground reads 0 (zero) when measured with an ohmmeter, the module

is defective and must be replaced.

Note

Return faulty modules to your local sales representative for

repair or replacement.

6.2.3 Software

If you are experiencing problems with the ROC800 that appear to be

software-related, try resetting the ROC800.

Caution

When you reset and subsequently re-start, the ROC800 loses

configuration and log data. BEFORE you attempt ANY type of reset,

back up your configuration and log data. Refer to

Preserving

Configuration and Log Data

in this chapter.

Warm Start

Use a

warm start

to restart without losing configuration or log data.

To perform a warm start, open ROCLINK 800 software, connect to the

ROC800, and select
