1. Objectives
This document is written for user to understand the system architecture of PCS and understand the normal operation on PCS. Most knowledge is based
on operation via Modbus TCP.
1.1. Application Notes
Before reading this documents, we suggest you read following notes for information inquiring first.
a) Inquiries are generally sorted as PERIODIC / WHEN NEED / FIRST RUN.
b) Recommended period for inquiring information is 200ms.
c) Recommended maximum length of inquiry data is less than 50.
d) Recommended period for inquiring measurements data is 500ms+.
e) The parameters of configurable parameters are Readable/Writable attribute, including registers related to grid code. After modifying
parameters, users can read them again to confirm whether the modification is successful.
f) In first co-test, a READ is recommended when a WRITE is applied.
g) All the parameter configuration steps in this article are described with the register address of the PCS (ID=1) as an example. For the scenario of
multiple PCS parallel applications, please refer to " Appendix B Status & Monitoring Variables Table" of PCS100HV Protocol.pdf for the more
registers information.

2. System architecture
In order to describe PCS operation, we define a general system architecture as follows. And the system mentioned in this document would be same as
follows. Notes would be added when different appears.

If step1 fail, execute step2 until step1 pass.
Check step3: 0x06F4 equal to ‘0x01’ - Pass,
If step3 fail, confirm what’s PCS state it is,
and fault state by corresponding methods.
If step3 pass, process step4.
Normally, step 1 and 2 could be ignored.
Final PCS state is ‘0x02’-Soft start GT mode.
Note: Every time the PCS is powered on
again, the initial value of this

Note: a time delay between command and next state request should be over 50ms.
Note2: PCS will respond the corresponding operation only after the system state enters normal operation. for example, the power demand commands
only available under the normal run state of grid-tied mode(0x03), Voltage and Frequency regulation only available under the normal run state of stand-
alone mode.
Note3: The time delay is an approximate time of execution of ONE PCS. It needs an additional about 3 seconds for each PCS for parallel system.
