piefum Posted October 7, 2014 Share Posted October 7, 2014 Hi all I have a problem configuring a small Ethercat IO network with a Power Brick LV. The ethercat devices connected to the PowerBrick are: (all beckhoff) - EK1100 (ethercat coupler) - 3x EL3204-0200 (4x RTD / PT1000 input) The Power PMAC System Setup recognizes the devices and I am able to read some registers, for example the 0x60n0:17 that are the analog RTD input. However, I need to configure some registers to make the EL3204 postprocess correctly the input (in fact the default readout is not the temperature). The configuration registers start from 0x8000, but I cannot access to them. I tried to load a proper XML configuration file (containing the definition of these registers) but the System Setup does not show them. I also tryed a manual readout of the registers via the command line, but I am still getting error messages ("Failed to read register: Input/output error"). Am I missing something? -- EDIT: ok, I set the proper value to the register using the command DOWNLOAD: ethercat -m0 -p 1 -t uint16 0x8000 0x19 0 where 0x8000 is my address, 0x19 the subindex and 0 the correct value. However, reg_write and reg_read still raise errors, and the System Setup tool is not able to recognize there addresses. thanks gg Link to comment Share on other sites More sharing options...
Omron Forums Support Posted October 7, 2014 Share Posted October 7, 2014 ...ok, I set the proper value to the register using the command DOWNLOAD: ethercat -m0 -p 1 -t uint16 0x8000 0x19 0 Try using: ethercat -m0 -p1 -t uint16 download 0x8000 0x19 0 When using a bkgrd plc, or a configuration file try using: L0=ecatsdo(0,1,$8000,$19,0,0) Note: there must be six parameters within the parens (...) even for reading. The first parameter is 0 for a write operation, or a 1 for a read operation. The second value from the end is the data to be written. Again, there must be a value here even when reading. I hope this helps. -m Link to comment Share on other sites More sharing options...
