1.3 Terms PLC: TPLC005 Terminals: MPNC020; MPNC030 Operator panel: TP1057 System: PLC (TPLC005) with Terminals TBUS: Internal communication bus between TPLC005 and terminals. 1.4 Security Attention Switch off devices before connecting them. Attention TPLC005 must be installed in closets or cabinets accessible only by qualified personnel through a key or a tool. ESD (Electrostatic Discharge) Modules have electronic components that can be damaged by. electrostatic discharge. Be sure to be connected to ground when handle the devices. The instrument has no power switch and no internal fuse, but...

2 Hardware installation 2.1 System description TPLC005 is a realtime PLC made up by a PLC and various terminals for several digital and analogue signals. The RS485 ModBus/RTU slave interface allows to the TPLC005 to communicate with a display panel to show the PLC variables. TPLC005 can be connected to analogue and digital terminals (MPNC020; MPNC030; the link between TPLC005 and terminals is an internal bus called TBUS. 2.2 Technical specification Table 1 Mechanical Material Dimension W x H x L Installation Environmental Condition Operative Temperature Storage Temperature Relative Humidity...

System must be installed with a space for heat dissipation and cabling. Avoid cabling superimposing to avoid EMC problems. 2.3.2 Component adding and removal Attention Be sure that devices are not powered when performing component adding or removal. The insertion and removal of a single terminal is made by using the hook at the base of the terminal as shown. The assembly must begin with the insertion of the TPLC005. After that, the required terminal are inserted in sequence. The DIN rail mounting is ensured by the spring coupling each terminal.

Adding terminals Removing terminals Figure 4: Adding and removing component Instruments must be connected on TBUS with the sequence shown in the figure. TPLC005 must be placed on the right and terminals on the left. All modules must be attached directly onto a DIN rail type EN 50022 (DIN 35) on which their TBUS connection modules were properly inserted. TBUS connection 9 ME7021_02 06/14

modules perform internal communication between the PLC (TPLC005) and terminals. modular connector DIN rail modular connector TBUS connection Figure 6: TBUS 3 TPLC005 wiring 3.1 Power supply 3.1.1 Isolation The system offers 3 different areas with galvanic isolation as represented in the picture below.

As shown in the above figure, on TPLC005 there is no galvanic isolation between power supply and internal TBUS. Only on each terminal there is a galvanic isolation to isolate the ground of the terminals. 3.1.2 System supply voltage TPLC005 system requires a supply voltage of 24VDC (-15% or +20 %) as shown in the picture. The system is protected from reverse polarity supply voltages. Caution Wrong Supply voltages can cause irreversible damages to the devices. 3.1.3 Digital outputs power supply Each digital output TPLC005 terminal can provide up to 2 A maximum current on 24V. The maximum...

The system has not internal fuses. It is recommended, for the protection of the TPLC005 input stage of the power supply, the usage of a 1A fuse, while for the power stage (terminal 2 black) 2,5A fuse. 3.1.5 Grounding The DIN rail that hosts the TPLC005 and the terminals must be thoroughly grounded in order to increase the resistance against electromagnetic interference. 3.1.6 Shielding To reduce system EMC sensitivity, the cable connecting the operator panel and TPLC005 must be a shielded cable connected to GND on both devices. 3.2 The daisy chain (DC) After power supply (system reset) the...

3.3 I/O wiring TPLC005 can be used stand alone, can be connected to a series of terminals of MPNC series and can be connected via ModBus to a graphical terminal. On TPLC005 there are: • 8 Input – software configurable Output • 2 software configurable universal Analogue Input In the figure below there are the terminal blocks for wiring the TPLC005.
