6.2.3. Freely Configurable Custom Modbus Map
It.is.possible.to.map.measured.value/status.registers.arbitrarily.in.a.block.with.up.to.20.registers.provided.for.
this purpose. This means that registers of interest may be mapped in an area with consecutive registers, so that
important values can be queried with a single command in one block.
The custom map can be configured via:
▪.
PCS10 Product Configuration Software and the USB configuration cable HA010327.
The PCS10 can be downloaded free of charge from www.epluse.com/pcs10 .
▪.
Modbus protocol commands, refer to the example in chapter 6.3 Modbus RTU Example.
The register block for the configuration of the customisable Modbus map consists of the registers 6001 (0x1770)
to 6010 (0x1779). For the blockwise query of the measured values behind Modbus registers 3001 (0xBB8) to
3020 (0xBCB), the firmware accesses this configuration area and thus gets the information which measured
value/status.registers.are.to.be.output..A.maximum.of.10.user-defined.registers.can.be.mapped..The.table.below.
