OVERVIEW
Fig. 3
The Nexgenie series is another 'first' from the Messung stable of innovative small sized PLCs. An unbelievable amount of features and combinations have been made available in a compact and ergonomic unit This PLC doubles as a PLC with limited function Human Machine Interface (HMI) (optional) and has around 4 basic variants of base unit and 5 variants of expansion units .Up to 4 expansion units can be cascaded to add more I/Os to any base unit The base unit comprises of minimum 14 I/Os and can be expanded up to 80 I/Os The PLC can be mounted on a standard DIN rail (35 mm x 7.5mm). Programming is achieved with the internationally acclaimed CoDeSys software that is compliant to the requirements of the PLC 'product standard' IEC/EN 61131-3. Users conversant with any of the following languages: Ladder Diagram (LD), Function Block Diagram (FBD), Structured Text (ST), Instruction List (IL) and Sequential Function Charts (SFC), Continuous Function Charts (CFCs) can comfortably program this PLC.
The figure 4 above shows recommended standard DIN rails TS 35 / 7.5 mm and figure 5 below shows back side view of base unit along with DIN clip.
MOUNTING
To mount the PLC on the DIN rail, 1) the DIN clip is to be pulled downwards till it clicks, 2) then the PLC is hooked on the rail and pressed down on the rail 3) and the DIN clip to be pushed upwards again till it clicks The unit will clamp on the rail with only slight horizontal slide movement. To prevent horizontal dislocation in transit or in anticipated vibration in the installation, the DIN rail mounted units may be locked in place using end clamps on either side. Recommended types: - ELMEX: SCKU / SCUN or CONNECTWELL: CA702/802/202 or WAGO 249-116/117

RECOMMENDATIONS
The PLC assembly is required to be panel mounted taking care of the following points Only horizontal mounting is permitted. Vertical or suspended from panel roof or floor mounting is not allowed for thermal considerations. The required clearances around the unit are given in figure 6 below. A 50 mm clearance is also required on the front side of the unit.

In case of small sized panels care shall be taken to keep more clearances on right side so as to facilitate proper viewing of the label on the underside of the flap. The unit is designed as an 'open type unit' which requires it to be installed in a suitable panel protecting from heat, dust and water. If only base unit (without any expansion unit) is installed, ensure that the terminator plug is fitted on expansion connector on its right side. The expansion units should be connected to the base unit in tandem with the supplied flat cables. It is necessary to remove terminator plug from Base unit and fix it on the last unit on its right side. This is mandatory for system operation. In case of possible vibrations/shocks to the panels in use, the unit shall be required to be protected from sliding movement in the rail by use of clamps from both sides of the unit to avoid dislocation of wires and connectors causing malfunction.

For performance that is least susceptible to external EMI the low voltage and high voltage noise prone wires should be physically isolated and laid out separately in the panel. In cases where crossing is found to be inevitable the cables should cross at right angles to avoid cross talk. A strip of paper of width 50mm or so is recommended to be wrapped around the unit sides during installation and wiring to avoid small pieces of wire ends or strands or washers or drilling burr et cetera from falling into the unit and getting trapped on boards causing severe damage mechanical or electrical shorts in the miniature electronic components on the boards. The paper should be removed without fail before putting the system in use Individual connector wires may be dressed to leave the unit from top and bottom sides so as to give natural isolation between input and output sides or clubbed together to leave from one side of unit.

User can select terminator resistor in RS485 network, by connecting pin 6 (TR selection) and pin 7 (D-RS485) together on D connector whenever required. Powering any external devices using VCC is not recommended.
For RS485 interface, Data+line is formed by connecting pin 4 (Tx+) and pin 9 (Rx+) together. Data- line is formed by connecting pin 7 (Tx-) and pin 8 (Rx-) together. User can select terminating resistor in RS485 network, by connecting pin 6 (TR selection) and pin 7 (Tx-RS422) together whenever required.

The figure shows how to interface PNP and NPN type of 3 wire proximity switches as an example in one of the inputs. In normal course where the proximity switch-off currents are below 1.5 mA the bleeder resistor would not be required. In case the off currents are greater that 1.5 ma typically the excess current would have to be bled through the bleeder resistor [Rb=Vin / (Ioff-1.5)] ( Rb in kilo-ohms Vin in Volts and Ioff in millamperes )
