CHAPTER 1 INTRODUCTION
1.3 Outline of product
SJ-PB(T) is Profibus-DP communication board for SJ300/L300P series inverter.
SJ300/L300P series inverter can get to connect another devices via Profibus-DP when install SJ-PB(T). SJ-PB(T) is possible to use for all models of SJ300/L300P series.
The SJ-PB(T) option board communicates according to the Profibus Protocol Standard DIN 19245 part 1 & 3. This means that it can communicate with all masters that comply with this standard, but it does not necessarily mean that all services available in the Profibus standard are supported. The “Profibus Profile for Variable Speed Drives” (order no. 3.072), also known as Profidrive, is a subset of Profibus which only supports the services relevant to speed control applications.
In a control system the option board will act as a slave that can be read and written to, from a Profibus-DP master. It will not initiate communication to other nodes, it will only respond to incoming telegrams.
(Note) RS485 communication function is disabled by installing SJ-PB(T) to the inverter.
Difference between SJ-PB and SJ-PBT is only connector for networking. Others are no difference.
