Product Introduction
3AFE61347089 YPK 118A Profibus-DP is an optional serial communication board at the APC2, enabling a PLC or PC (Master station) to control frequency converters or DC drives through the Profibus-DP communication channel. The YPK 118A board is the same as the SNAT 7700 PRI but contains a different EPROM.

Product Details
The YPK 118A 3AFE61347089 Communication is based on the Profibus-DP protocol, specified in DIN 19245, part 3, PROFIDRIVE, Profibus profile for adjustable speed drives. With the SNAT 7700 PRI board, you can use the Profibus-DP protocol up to 1.5 MBaud.
X1: iSBX bus connector
X2, X3: D-connectors for Profibus communication
S300: Bus termination selection
S302: Connects X2 and X3 i.e. bus chaining
D201: EPROM-circuit containing APC2 Profibus-DP
software. (The label text is e.g. YPK 118 D201
Rev: A 96-09-02)
Red LED: The LED is on when communication between the
master and the Profibus interface (slave) is OK.
The LED starts blinking if communication fails.
Green led: Indicates that the Profibus interface has just
received or sent a message.
Profibus is based on RS-485 differential (balanced) data transmission over a single twisted pair line. To guarantee reliable communication at high transfer rates, the bus cable must be correctly terminated.
The switch S300 on the YPK 118 card is used to control termination.
