6.4 Modbus communication information

Access to communicated information

Each status indication or measurement displayed on the module is accessible via the RS232 or RS485 communication port.

Each PMM module uses a series of 16 addresses.

If the network communicates with a number of PMM modules, use an available series among the following series of 16 addresses for each module: 1 to 16 ,17 to 32, 33 to 48, 49 to 64, 65 to 80, 81 to 96, 97 to 112, 113 to 128, 129 to 144, 145 to 160, 161 to 176, 177 to 192, 193 to 208, 209 to 224 and 225 to 241.

The 16 addresses in each series are assigned the following functions: 1st address in the series: reserved for MGE UPS SYSTEMS,

2nd address in the series: access to card BCM1 (status and measurements for output circuits of phase A), 3rd address in the series: access to card BCM2 (status and measurements for output circuits of B), 4th address in the series: access to card BCM3 (status and measurements for output circuits of C),

5th to 8th address in the series: reserved for MGE UPS SYSTEMS, 9th address in the series: access to card MCM (general status and measurements), 10th to 16th address in the series: reserved for MGE UPS SYSTEMS.

As indicated above, four addresses in each series are used to access the information in the registers of four cards, corresponding to all the status and measurement information presented in the tables on the following pages.

Key for tables: # : register using 2 bytes, R/W : read only (R ) or read/write (R/W ) information, Bit : detail of each bit of the address, NV : non-volatile information, Description : description of the concerned information.

Additional explications are provided in the right-hand column if necessary.

Each element represents the value in mA of the current in the given output circuit.

This register provides a rapid overview of the status of the alarms on the card. The global alarm bit is 1 if any one of the 16 bits of the indicated register is 1.

These bits go to 1 when the current in a corresponding output circuit is greater than the minor alarm threshold (60% in the example opposite) and less than the major alarm threshold (80% in the example opposite). This state is stored in memory until the alarm is reset by setting the bit to 0.

These registers define the minor alarm thresholds. A minor alarm occurs when the current in a given output circuit is greater than the minor alarm threshold and less than the major alarm threshold for a duration exceeding the minor alarm time delay. The units are in % (60 = 60%). The setting range is from 0 to 100. The factory setting is 60. A minor alarm is not activated if the current goes instantaneously from one threshold to the other.
