- Page 12 2.2 Power Requirements Both the Gateway models are DC powered. The specified voltage range for gateway-EP model is +24VDC + 5%. For Gateway-PP models power is supplied from the PLC port cable and the supply voltage range is +5VDC + 5%. Make sure to check PLC power before connecting cable to Gateway-PP models.
- Page 13 DC voltage sources should provide proper isolation from main AC power and similar hazards. 2.3 Communication ports Each Gateway unit has two communication ports . Description of each is given in following topics. Com port1: This port is RS232C port and is used for configuration of gateway. Same port can be used for PLC communication after proper configuration.
- Page 14 Com port2: This port is RS232C or RS485 (2 wire) depending upon ordering information and is used for PLC communication. For Gateway-EP RS232C EARTH SUPPLY GND +24 VDC +/- 5 % IN SIGNAL GROUND RS485 EARTH SUPPLY GND +24 VDC +/- 5 % IN...

Page 16: Getting Started
Getting Started In this chapter..Introduction Project – Devices, Register Address and Blocks, Device communication... - Page 17 Each register in a device memory has a unique address and this address can be directly used in Gateway project. Each action to be taken by Gateway, which is configured in a Project, is known as a Block. Block may contain information like, copy number of Words, Bits etc from Source device to Destination device.
- Page 18 If Gateway is of type Gateway-PP then communication cable Pin-outs should be as follows. DB9 (Male) DB9 (Female) for IBM-PC 2--------------------------------------------------2 3--------------------------------------------------3 5--------------------------------------------------5 +5 VDC 6 -- +5 VDC Gateway - device Communication Cable: Proper Gateway - device cable is required for error free communication with any device.

Gateway Features In this chapter..Repeat Cycle Control Word Error Indication Bit Selectable Baud rate LEDs for Communication Status... - Page 20 Repeat Cycle =99 …………Lowest priority Normally, Blocks are executes in step by step fashion. Eg. If 5 Blocks are defined a in project with Repeat cycle = 1, then Gateway executes blocks in following fashion. Block execution starts with Block#01, then Block#02, … Block#5 and...
- Page 21 Another way of controlling Block execution is use of Control Word. This feature is extremely useful for small applications where less than 17 blocks are required. Control Word can be enable or disable while configuration of Gateway using Configuration Software. Normally Control Word is disable. It can enable just by clicking on check box in setup software.
- Page 22 Normally this bit is “OFF”, in case of abnormality in communication. This bit is set to “ON” by gateway , so that external device can know the problem. This useful to operator to take necessary action and avoid production losses.
- Page 23 When proper PLC-Gateway Cable is connected and power is applied to Gateway, and if external Device is not responding or power is not applied to external Device or Communication cable is faulty, then this LED will blink at slow rate.
