3.5.3 Data exchanged through Fieldbus
The following table details the data exchanged through the Fieldbus communication:
WARNING! The system is in alarm if the "control unit status" byte of the "System configuration and
status" module PS2v6 or PS2v4 is different from "0xFF".
Data type Description
Communication
direction
Safe SYSTEM STATUS DATA
ISC-B01 control unit:
l internal status
l status of each of the four outputs
l status of each of the two inputs
LBK-S01 sensor:
l status of each detection field (target detected or not) or error status
l muting status
from the control
unit
Safe SYSTEM SETTING COMMAND
ISC-B01 control unit:
l set the ID of the dynamic configuration that shall be activated
l set the status of each of the four outputs
l fix the current accelerometer information
l enable the restart signal
LBK-S01 sensor:
l set the muting status
to the control unit
Safe DYNAMIC CONFIGURATION STATUS
l ID of the dynamic configuration currently active
l signature (CRC32) of the dynamic configuration ID currently active
from the control
unit
Safe TARGET DATA
l Current distance of the target detected by each sensor connected
to the control unit. For each sensor, only the closest target to the
sensor is considered.
from the control
unit
Unsafe DIAGNOSTIC DATA
ISC-B01 control unit:
l internal status with an extended description of the error condition
LBK-S01 sensor:
l internal status with an extended description of the error condition
from the control
unit
Unsafe SYSTEMSTATUSANDTARGET DATA from the control
unit
3.6 Modbus communication
3.6.1 Modbus support
The Modbus communication uses the Ethernet port (Modbus TCP) and consequently is only available for ISC-B01
and ISC-02 control units.
3.6.2 Modbus communication enabling
In the Inxpect Safety application, click on Settings > Modbus Parameters > ON to enable the feature.
Within the Ethernet network, the control unit acts like a server. The client must send requests to the IP address
of the server on the Modbus listening port (default port is 502).
