Compatibility

Compatible with EpiSensor Edge over Modbus TCP or Modbus RTU

The Shark 100 and Shark 100T are compatible with EpiSensor Edge over Modbus RTU on the RS-485 port of the 485P option, read through a ZMB-31 Modbus Interface or a Gateway serial port, and over Modbus TCP on a Shark 100 fitted with the INP10 10/100BaseT option. EIG publishes the register map with hex and decimal addresses, data formats, word order, ranges and units in Appendix B of the manual.

Shark 100 with the 485P or INP10 communication option and the Shark 100T transducer, using the Modbus map in Appendix B of manual E145701 V.1.40. Site check: read Meter Type at hex address 0010 for the V-Switch, then compare Volts A-N with the display. Read-only monitoring: no writes to the commands section or the programmable settings.

Interface

Documented measurements and integration boundaries for Shark 100.

• Every row of the map gives a hex address and a decimal register number: Volts A-N is hex 03E7 to 03E8 and decimal 1000 to 1001. The hex value is the address sent in the Modbus frame, and the decimal number is that address plus one. The manual does not list function codes; Edge reads the map with FC03, and the Meter Type read in the worked example confirms the meter answers it.
• FLOAT is a 32-bit IEEE value in two registers and SINT32 or UINT32 a 32-bit integer in two registers. For both, the manual states that the lower-addressed register is the high-order half.
• Primary readings, FLOAT, in the map's 60-cycle block: Volts A-N, B-N and C-N at registers 1000, 1002 and 1004 (hex 03E7, 03E9, 03EB) and A-B, B-C and C-A at 1006, 1008 and 1010, in volts; Amps A, B and C at 1012, 1014 and 1016 in amps; neutral current at 1028.
• Three-phase totals, FLOAT: watts at 1018 (hex 03F9), VARs at 1020, VAs at 1022, power factor at 1024 (-1.00 to +1.00) and frequency at 1026 (hex 0401) in Hz. Power is in watts, not kilowatts. The map has no per-phase power.
• A faster copy of watts, VARs and VAs, averaged over 6 cycles, sits at registers 900, 902 and 904 (hex 0383, 0385, 0387) as FLOAT.
• Energy, SINT32 with an implied decimal point: W-hours received 1100 (hex 044B), delivered 1102, net 1104 and total 1106; VAR-hours positive 1108, negative 1110, net 1112 and total 1114; VA-hours total 1116. Each counter holds 5 to 8 digits.
• Energy scale comes from the Power & Energy Format register 30006 (hex 7535), bit-mapped pppp--nn -eee-ddd: eee is the energy scale (0 units, 3 kilo, 6 mega) and ddd the digits after the decimal point (0 to 6). The value in Wh is the register divided by 10 to the power ddd, times 10 to the power eee.
• Wh received and Wh delivered always have opposite signs. Received is positive when the meter is set to view as load and delivered is positive when it is set to view as generator (power direction bit w in register 30015).
• Fixed data: Meter Name at registers 1 to 8 and serial number at 9 to 16 as ASCII, two characters per register; Meter Type at 17 (hex 0010) with bit t set for the transducer model and the V-Switch number 1 to 4 in the low three bits; firmware version at 18 to 19 and map version at 20.
• V-Switch sets the readings: V1 volts and amps, V2 adds watts, VARs, VAs, power factor and frequency, V3 adds the Wh, VARh and VAh counters, and V4 adds %THD and limits. THD at 4000 to 4005 is UINT16 in 0.1% and reads 65535 when not available.
• Demand averages are at 2000 to 2019, minimums at 3000 to 3033 and maximums at 3100 to 3133, all FLOAT. Phase angles at 4100 to 4105 are SINT16 in 0.1 degree.
• Meter Status at register 5000 (hex 1387) holds the state in its low byte: 1 is Run and 2 is Limp. Meter Data Section registers read 0 until the first readings are available or when the meter is not in operating mode, and unlisted registers also read 0, so do not store a run of zeros as a measurement.
• The Secondary Readings block from 40001 carries 12-bit values from 0 to 4095 with fixed offsets (Volts A-N 2047 is 0 V and 4095 is 150 V). It is meant for analogue-style transducer use; read the primary floats instead.
• Write registers: reset max/min 20000, reset energy 20001 and 40100, programmable settings 22000 to 22004, firmware reprogramming 23000, forced restart 25000, secure operations 26000 to 26011 (an encrypted command to read the password or change the meter type) and the settings block 30000 to 30067. The meter ships with passwords disabled and has no default password; the map says to use 5555 as the password while passwords are disabled. Keep all of them out of a monitoring poll.

Setup

1. Identify the meter and its options

   Read the order code on the label. The meter needs COM option 485P (or INP10 for Ethernet); a Shark 100 with COM option X has only the front IrDA port. Note the V-Switch, because power and frequency need V2 and the energy counters need V3.

2. Read the port settings

   On a Shark 100, Configuration mode shows the PORT screens: address (Adr), baud rate (bAUd) and protocol (Prot), which must be set to Modbus RTU. From the factory the port runs at 57600 baud, address 001. A Shark 100T has no display, so read its profile with EIG's CommunicatorPQA software. Enter the same address and baud rate, with 8 data bits and no parity, in the Edge serial client or the ZMB-31.

3. Wire the RS-485 pair

   Connect + to +, - to - and the shield to SH on the meter's RS-485 terminals with shielded twisted pair, ground the shield at one end and daisy-chain any further meters without stubs.

4. Confirm the meter and its V-Switch

   Send FC03 for one register to hex address 0010, the Meter Type register. The low three bits give the V-Switch (1 to 4), and bit 8 is set on a Shark 100T.

5. Compare one value with the display

   Read Volts A-N from hex 03E7 as a float with the high word first and compare it with the VOLTS L-N screen, then add current, power, frequency and, on V3 or V4, the energy counters.

6. Scale the energy counters

   Read the Power & Energy Format register at hex 7535 once, apply its energy scale and decimal digits to the Wh and VARh counters, and compare Wh received with the display. Never write to the commands section or the settings block.

Common questions

Do I send the hex or the decimal address from the Shark 100 map?

Send the hex value. Every row of EIG's map gives both: Volts A-N is hex 03E7, which is decimal register 1000. The hex column is the address in the Modbus frame and the decimal column is that address plus one, so a tool that numbers registers from one takes 1000.¹

Why does the Shark 100 not show power or energy over Modbus?

Check the V-Switch. Meter Type at register 17 (hex 0010) holds it in the low three bits: V1 is volts and amps only, V2 adds power, power factor and frequency, and V3 adds the energy counters. The map also says meter data registers read 0 until the first readings are available or when the meter is not in operating mode.^1, 2

How do I scale the Shark 100 energy registers?

The Wh, VARh and VAh counters from register 1100 are SINT32 integers with an implied decimal point. Read register 30006 (hex 7535): bits 6 to 4 give the energy scale (0 units, 3 kilo, 6 mega) and bits 2 to 0 the digits after the decimal point. A counter of 123456 with kilo and one decimal digit is 12345.6 kWh. The map notes that energy registers should be reset after a format change, so read the format register again if the counters change scale.¹

Does the Shark 100 separate imported and exported energy?

Yes. W-hours received at register 1100 and delivered at 1102 are separate counters with opposite signs, with net at 1104 and total at 1106; VAR-hours have positive and negative counters at 1108 and 1110. Which direction counts as received depends on the power direction setting: received is positive for view as load and delivered is positive for view as generator.¹

Does the Shark 100 have Modbus TCP?

Only with the INP10 option, a 10/100BaseT Ethernet card for Modbus TCP/IP. Manual V.1.40 sets the card up over Telnet on port 9999 from its factory address 10.0.0.1 and takes the Modbus address from the unit identifier in each request. The 485P option gives the RS-485 port instead, the front IrDA port speaks Modbus ASCII only, and a meter ordered with COM option X has no rear port.^1, 2

How do I find the settings of a Shark 100T with no display?

Use EIG's CommunicatorPQA software over the RS-485 port. The manual describes a default communication mode: poll the meter within 5 seconds of power-up at 9600 baud, address 001, with Modbus RTU, and it keeps those settings until 5 minutes pass with no activity, long enough to read its programmed address and baud rate. Then set the same values in Edge.¹
