TRIO-20.0(27.6)-TL-OUTD Modbus RTU Registers Map – Revision GT04

General liability warnings concerning inverter use Please refer to the TRIO-20.0(27.6)-TL-OUTD Product Manual for complete installation instructions and product use. ABB accepts no liability for failure to comply with the instructions for correct installation and will not be held responsible for systems upstream or downstream the equipment it has supplied. It is absolutely forbidden to modify the equipment. Any modification, manipulation, or alteration not expressly agreed with the manufacturer, concerning either hardware or software, shall result in the immediate cancellation of the warranty. The Customer is fully liable for any modifications made to the system. Given the countless array of system configurations and installation environments possible, it is essential to check the following: sufficient space suitable for housing the equipment; airborne noise produced depending on the environment; potential flammability hazards. ABB will NOT be held liable for defects or malfunctions arising from: improper use of the equipment; deterioration resulting from transportation or particular environmental conditions; performing maintenance incorrectly or not at all; tampering or unsafe repairs; use or installation by unqualified persons. ABB will NOT be held responsible for the disposal of: displays, cables, batteries, accumulators etc. The Customer shall therefore arrange for the disposal of substances potentially harmful to the environment in accordance with the legislation in force in the country of installation.

Field of use, general conditions ABB shall not be liable for any damages whatsoever that may result from incorrect or careless operations. You may not use the equipment for a use that does not conform to that provided for in the field of use. The equipment MUST NOT be used by inexperienced staff, or even experienced staff if carrying out operations on the equipment that fail to comply with the indications in this manual and enclosed documentation.

Intended or allowed use This equipment is a multi string inverter designed for: transforming a continuous electrical current (DC) supplied by a photovoltaic generator (FV) in an alternating electrical current (AC) suitable for feeding into the public distribution network.

12. Holding registers 0190 and 0503 (Power ramping interval): Time reference for manage the transient when a new set-point is applied. If 1s step is selected in the holding register 0198 or 0505, the global value is composed by the following formula: (Nx1sec) + (Mx10ms) where N and M are the lower and higher byte: M (10ms step) = MSB; range 0 to 99 [0s to 990ms] N (1s step) = LSB; range 0 to 250 [0s to 250s] If 4s step is selected in the holding register 0198 or 0505, the global value is composed by the following formula: (Nx4sec) + (Mx10ms) - 19 -

TRIO-20.0(27.6)-TL-OUTD Modbus RTU Register Map

where N and M are the lower and higher byte: M (10ms step) = MSB; range 0 to 99 [0s to 990ms] N (4s step) = LSB; range 0 to 62 [0s to 248s] It defines transient duration or transient slope depending on the transient mode selected (register 0198 or 0505). If it is defined as duration, it represents the real duration of the transient (any variation is applied with variable slope to have a fixed duration for each delta). If it is defined as slope, it represents the time duration of the rail to rail transient (any transient is applied with constant slope and duration related to the delta). The default value is 15 (N=15;M=0) [60s]. 13. Holding registers 0198 and 0505 (Set transient options): The global value is composed as follows: Transient step = MSB; range 0 to 1 [0 = 4s step; 1 = 1s step] Transient mode = LSB; range 0 or 128 [0 = Slope mode; 128 = Duration mode] The default value is 0 [Slope mode;4s step]. Duration mode and 1s step may be set only if register 0299 is set to 1 (transient options configurable).
