↑ Solidot CC-Link IE Field Basic Slice I/O Coupler KitXB6-CB2002ST
When the Solidot XB6 series I/O modules are adapted to a CC-Link IE Field Basic master, each channel of a digital I/O module occupies 1 bit, and the fixed data length is 4 bytes (= 32 bits), which is the data length of one XB6-3200A. Therefore, digital modules use the same "32-bit mold".
1. According to this rule, the following two cases can be distinguished. Let us first look at digital I/O modules
1. Point allocation for pure-input digital I/O modules
XB6-1600A occupies 32 points, but actually uses the first 16 points; the last 16 points are unused (reserved). XB6-0800A actually uses the first 8 points, and the last 24 points are unused (reserved). The same applies to output modules.
2. Point allocation for mixed input/output digital I/O modules
For XB6-1616A, the Upstream RX occupies 32 points, actually using the first 16 points, with the last 16 points unused (reserved); the Downstream RY occupies 32 points, actually using the first 16 points, with the last 16 points unused (reserved). Therefore, when two XB6-1616A modules are connected together, the Upstream RX of the second I/O module must be offset by the number of unused (reserved) points of the previous I/O module, as shown in the figure below:
2. Now let us look at analog I/O modules
The analog I/O modules of the Solidot XB6 series include XB6-A80V, XB6-A40V, XB6-A08V, XB6-A04V, XB6-A80I, XB6-A40I, XB6-A08I and XB6-A04I. In actual use, each channel occupies 1 word, so an 8-channel analog I/O module occupies 8 words, and a 4-channel analog I/O module is the same as an 8-channel analog I/O module, also occupying 8 words. Therefore, XB6-A40V occupies 8 words, actually using the first 4 channels, with the last 4 channels unused (reserved). When the Coupler XB6-CB2002ST connects one XB6-A04V and one XB6-A08V, the mapping address arrangement is as shown in the figure below:
note:
1. XB6-A80TM and XB6-A40TM follow the same principle;
2. The mapping addresses of function modules such as XB6-P04A do not follow the above rules. For details, visit the Solidot official website, search for the required model, and refer to the relevant user manual.
