Indramat SIS Protocol

Overview

The Indramat SIS serial downloadable protocol is for communication between the Indramat SIS drives and an OCS. This is a Master/Slave protocol.

CSCAPE Configuration

To configure OCS for the IndramatSIS.dll 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 IndramatSIS.dll file is in the Protocols directory of the current working/open Cscape.

Serial Port Format

The default link settings are : 9600 baud, No parity, Eight data bits and RS232 communication mode.

Baud Rate can be changed via the P-0-4021 parameter.

Station Node Address

The station node address for the drive is specified as selected by the switches on the drive, and can changed by accessing the P-0-4022 parameter.

Commands

Each drive parameter is accessed as described in the Parameter Access manual available from Bosch-Rexroth. When these commands are being accessed in CSCAPE the name of each parameter can be directly accessed and the lists and strings accessed via its appropriate method in Cscape Protocol Configuration.

A Protocol Configuration step-by-step guide for CSCAPE is given later in this help.

Description of Register Types

Parameters - These register types access all parameters as numeric entries. Twelve options are available to the user. S-0 Parameter, S-7 Parameter, P-0 Parameter and P-7 Parameter as well as their maximum and minimum values that are stored in the drive.

DWORD Lists ( 4-Byte Variable Lists)

This type of register contains all the parameters that have its format as 4-Byte variable lists. There are 18 of them in all and they are accessed as follows:

Description of the DLL for use with the OCS range in CSCAPE

This section explains the DLL that is used to access data available with the Indramat SIS protocol.

In the Scan List when a parameter is added a window pops up the various options available for accessing.

The S-0, S-7, P-0 and P-7 Parameters can be selected using the radio buttons. The min and max value are of course accessible.

The Lists are by default, grayed out. But when selected, a drop down list of each of the lists is available. The item is the offset in to the list with which the user wants to access.

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	Invalid size for data type.
NO_RESPONSE_FROM_PLC	-204	Timeout while waiting for remote node response.
INVALID_RESPONSE_FROM_PLC	-205	Corrupted response from remote node.
INVALID_INITIALISATION	-207	Internal Error - Unable to open port.
