KELLER Series-30 Protocol
See also: Help for Serial Protocols
Overview
The KELLER serial downloadable protocol is for communication between the Keller and an OCS. This is a Master/Slave protocol.
CSCAPE Configuration
To configure OCS for the Mitsubishi protocol, select the Protocol Configuration from the Program menu in CSCAPE software. Select the appropriate protocol type on the desired port. To make sure that the Software is able to configure the equipment for the correct protocol, ensure KellerSeries30.dll file is in the Protocols directory of the current working/open Cscape.
Serial Port Configuration
The default link settings for the terminal are : 9600 baud, None parity, Eight data bits, Two stop bit, RS232 communication and No handshaking.
Data Mapping
Enter the desired parameter address in the Device Register field or use " > "button to select the desired parameter from the drop-down list. There are two drop-down lists viz. Function and Parameter Name.

Network Communication Errors
In order to access the Network statistics, user must assign the “Network status register” in network configuration. The table below gives the details of statistics.
Number | Statistics | Location | Description |
---|---|---|---|
|
|
|
|
1 |
Update interval exceeded count |
%Rx |
This register explains number of times that the actual transaction scan time to complete all transactions exceeded specified update interval. Generally used as an indicator that an excessive number of triggered transfers or failed communication retries are occurring that is lengthening the expected transaction scan time.
If the Update interval is set to zero (update as fast as possible), this 32-bit register alternately specifies the actual transaction scan time in mSec resolution. |
2 |
No response count |
%R(x+2) |
This register explains number of times that a device(s) did not respond to a transaction. This includes ALL failed transaction, not just those after the retry count is exceeded. |
3 |
Corrupt Response Count |
%R(x+4) |
This register explains number of times that a device(s) returned an invalid or failed response to a transaction. This includes ALL failed.
Transaction, not just those after the retry count is exceeded. |
4 |
Valid Response Count |
%R(x+6) |
This register explains total number of valid responses. |
NOTE: %Rx: 32-bit network status register configured in Network configuration. For example: %R500(501).
Device Communication Errors
Error | Error Number | Description |
---|---|---|
INVALID_BLOCK |
-203 |
