4 Connections
The ePALM10 is available in several versions, featuring different communication cables and different
solutions for the enabling switches.
4.1 Serial Communication - Types –0061 and –0062
ePALM types –0061 and -0062 include all standard UniOP connections and are suitable for all
common serial communication links.
The ePALM10-0061 includes a communication cable with a length of 5 meters.
The ePALM10-0062 includes a communication cable with a length of 10 meters.
The cable does not have a connector at its loose end as it is intended to be wired directly in the control
cabinet.
The following groups of signals are available in the cable:
PC/Printer Port
PLC Port
Aux Port
Power
Emergency Stop button – two NC contacts
Two 2-positions enabling switches – NO contacts
In all the most common configurations, the signals are wired to the cable and there will be no need to
open the unit to access the terminal blocks.
Note: the ePALM10 unit does not include a current loop (20 mA) interface in the PLC port. The
communication modules TCM04 (Interbus), TCM07 (Simatic S7 MPI without optical
insulation), TCM08/TCM18 (Profibus DP) and TCM10/SCM11 (Ethernet) are not supported.
Internally to the product all signals, excluding emergency stop, are wired to a detachable interface
board with five terminal blocks.
The position of the terminal blocks and the numbering of the contacts are shown in the figure below.
