MODBUS NETWORK (SD230 Only)
Description
The SD230 features network communications capability, either directly over Modbus to a Pro-face HMI
or indirectly through a gateway (ET230) to Ethernet/IP connected PLCs and HMIs. The network
connection provides access to all status information from the SD230, allows for remote activation of the
calibrate function, and if TriSense mode is enabled, full access to LH200 configuration, operation, and
result data. Additionally, diagnostic functions may be invoked and profiles of tested shells may be
displayed.
The SD230 units, when daisy-chained on the Modbus network, automatically assign their own device ID
numbers starting with 01 for the left channel of the unit connected to the HMI or gateway, through N
for the right channel of the last unit in the chain. For a four-out press, the assigned IDs would be from 01
through 08. The device ID appears on the two-digit display in the lower half of the front panel of the
SD230.
The bicolor LEDs located adjacent to the network connectors on the SD230, indicate status of the
communication with the channel on which they appear. The LED flashes yellow when a packet is
received and green when a packet is transmitted and a momentary red when a CRC or bad function
error occurs.
For details of Pro-face HMI operation see SD230 Pro-face HMI User Instructions.
Installation
Standard five conductor M12 male-female cables are used to daisy-chain from one SD230 unit to the
next. The daisy-chain cables are typically Prime Controls part number CBL112-1 for 0.3 meter or CBL112-
2 for 2 meters. The cable requirement to the left channel of the lead unit depends upon the device
being connected. The figures that follow show the cable required from the SD230 to a Pro-face HMI and
from the SD230 to the ET230 gateway. Part number choices for the SD230 to Pro-face HMI cable are
CBL230-HMI-2 (2 meter, no field attachable connectors), or a CBL230-HMI-X-FA with field attachable
M12 connectors for easier routing through conduits. The -X- is ordered as a 2, 5, or 10 for convenient
lengths in meters.
Setup
Setup of the SD230 units for networking requires only that DIP SW7 is ON when the units are powered
up and that the appropriate five conductor cables connect all units in a daisy-chain configuration. When
setup is complete, at power up the units display their ID numbers from on to 2xN where N is the number
of SD230 units connected together.
TriSense functionality requires wiring the LH200 serial signals to the SD230 via the AS230-RJ breakout
board and CBL230 cable. Optionally, the SL100 Flash Detect signal may be connected to the AUX2+ input
of the SD230 for confirmation of SL100 operation as well.
